Marijuana Prescription
Effects on developing fetus:
What are the physiological effects of marijuana?
Two important things to keep in mind!
- Marijuana is currently illegal, and this directly affects the productivity of potential social or clinical research
- In existing studies,
correlation =/= causation !
No. It can be recommended by a physician.

A physician must write a letter explaining the patient's diagnosis and the physician’s choice of cannabis as treatment. 

Is Marijuana Prescribed?
Medical Marijuana Card (MMIC)
Psychoactive Drugs
Substances that alter mental functioning

What are the health effects of marijuana?
Legalization of Marijuana
Changing tides in legislation
Over the past 20 years, 18 states + DC have legalized medical marijuana
In the past year, Colorado and Washington have legalized marijuana for recreational use
California, Arizona, Oregon, Alaska, and other states are currently seeking voter approval of ballots to approve legalization of marijuana
Trends in Public Opinion
Reasons for Drug Use
Why are more people supporting legalization
of marijuana?
Perceived personal benefits to mood
Escape/Relieve psychic distress
Religious or Cultural ceremonial practice
Treatment of illness and disease
New Age thinking -- a steady progression
towards legalization
Attempts at Legalization in California
Drug Use Can Be Harmful
Legal History of Cannabis
the regulation of marijuana for recreational or medical purposes in the US
1910: States Outlaw Marijuana First
1910: The Mexican Revolution caused an influx of Mexican immigrants. Officials feared they would introduce the habit of recreational use into American society.

Bolstered by Progressive Era faith in big government, the 1910s marked a high tide of prohibitionist sentiment in America.

1915-1927 - 10 States Pass Marijuana Prohibition Laws

"[In 1915] Utah passes state anti-marijuana law...
Other states quickly followed suit with marijuana prohibition laws, including Wyoming (1915), Texas (1919), Iowa (1923), Nevada (1923), Oregon (1923), Washington (1923), Arkansas (1923), and Nebraska (1927)." The state of New York outlaws cannabis in 1927.

1915: Foundation for Federal Drug Regulation
1915 - President Wilson Signs Harrison Act, the Model for Future Drug Regulation Legislation

Representative Francis B. Harrison wanted to regulate the opium trade, and therefore introduced three bills in 1913 to remedy the [drug] problem

Although it does not apply to marijuana, the Harrison Act becomes the model for drug regulation on the federal level and is considered the basis for the Marihuana Tax Act of 1937.

Hemp Production Encouraged

Marijuana vs. Hemp vs. Cannabis

American production of hemp was encouraged by the government in the 17th century for the production of rope, sails, and clothing.

In 1619 the Virginia Assembly passed legislation requiring every farmer to grow hemp. Hemp was allowed to be exchanged as legal tender in Pennsylvania, Virginia, and Maryland.

1906: Strengthening of Poison Laws

The Pure Food and Drug Act:
-passed by the United States Congress in 1906
-required that certain special drugs, including those with cannabis, be accurately labeled with contents.

Further regulation of cannabis followed in:
Massachusetts (1911)
New York (1914)
Maine (1914)

In New York, reform legislation began under the Towns-Boylan Act, which targeted all "habit-forming drugs", restricted their sale, prohibited refills in order to prevent habituation, prohibited sale to people with a habit, and prohibited doctors who were themselves habituated from selling them.

1936 - Reefer Madness Film Cautions Against Marijuana

"Reefer Madness is a morality tale of how Reefer Addiction ruins
the life of its young protagonist and gets a lot of other people
killed, sexually compromised and committed to lunatic asylums..."

Financed by a small church group

Purchased for exploitation by Dwain Esper who changed the title
and added salacious insert shots

Other films included:
Esper's own Marihuana (1936)
Elmer Clifton's Assassin of Youth (1937)

1936: Reefer Madness

Spectrum of Psychoactive Substance Use
Marijuana Awareness Programs
No current medication for marijuana addiction

Court- mandated educational class as part of the fulfillment for marijuana-related misdemeanor

Goal: preventing future offenses

Marijuana Tax Act (1937)
The Marijuana Tax Act created a tax equaling roughly one dollar for anyone who dealt commercially in cannabis, hemp, or marijuana.
The Act did not itself criminalize the possession or usage of hemp, marijuana, or cannabis.
It did include penalty and enforcement provisions to which marijuana, cannabis, or hemp handlers were subject.

Oct. 2, 1937 - First Marijuana Seller Convicted under US Federal Law Is Arrested
The same day the Marijuana Tax Stamp Act was enacted,
Samuel R. Caldwell was arrested for a quarter ounce of marijuana:

-18 month prison sentence
-4 years of hard labour in Leavenworth Penitentiary
-$1,000 fine

"I consider marijuana the worst of all narcotics, far worse than the use of morphine or cocaine. Under its influence men become beasts. Marijuana destroys life itself. I have no sympathy with those who sell this weed. The government is going to enforce this new law to the letter." Samuel Caldwell was given four years hard labor in Leavenworth and fined $1,000.

1951 - Boggs Act Establishes Minimum Prison Sentences for Simple Possession
Mandatory sentencing and further punishment were mandated after the Boggs Act of 1952 and the Narcotics

Control Act of 1956
-first-time cannabis possession offense a minimum of two to ten years with a fine up to $20,000

-however in 1970 the United States Congress repealed mandatory penalties for cannabis offenses.

1970 - Controlled Substances Act Classifies Marijuana as a Drug with "No Accepted Medical Use"
Physiological signs of using marijuana include:
- Rapid heart rate
- Increased blood pressure
- Increased rate of breathing
- Red eyes
- Dry mouth

Psychological effects:
- Distorted sense of time
- Slowed reaction time
- Paranoia, fear, distrust, panic
- Short-term memory loss

** Large doses may lead to symptoms such as: acute psychosis, hallucinations, delusions


Marijuana is not FDA -approved!
Danger To Oneself and Others
-Stoned driving and other dangers would be increased.

-More widespread use would increase the dangers of secondhand smoke-damage to bystanders
Decreased Perception Of Risk
In Youths

"According to the 2009 National Survey on Drug Use and Health, past‐month marijuana use among 12‐ to 17‐year‐olds climbed 9 percent from 2008 (6.7%) to 2009 (7.3%)"
-Marijuana is associated with dependence and the smoke causes respiratory illnesses

-Marijuana has been associated with schizophrenia and depression.
Little Effect on Drug Cartels/ Violence
With such high taxes on marijuana and the increase in demand after legalization, drug cartels could simply lower their prices to keep their market share.

Marijuana is only a portion of the profit made from black markets. Organizations would continue to operate from other drug distribution, human trafficking, and other crimes.
High Social Costs
Alcohol and tobacco (substances that are legal and taxes) create a larger social cost for the United States than the revenue they generate.

Tobacco (2007)
Excise taxes Generated: $25 billion
Social Cost: $200 billion

Alcohol (2007)
Taxes Generated: $9 billion
Social Cost: $185 billion

-374,000 people entering an emergency room annually with a primary marijuana problem.

*"in alcohol‐related costs to health care, criminal justice, and the workplace in lost productivity."
Comparison of the harms of various drugs
Legalization in Colorado
15% excise tax and 10% sales tax
No cap on total amount of marijuana produced per year by state
Requires vertical integration
2-year minimum residency requirement for any owner or investor
Cultivation for personal use is allowed

Legalization in Washington
25% tax on all pot production
Cap on the total amount of marijuana that can be produced per year in the state
Prohibits "vertical integration"
3-month minimum-residency requirement for any owner or investor
Prohibit out-of-state investment in the growth and production of marijuana
Limit on the number of sellers' licenses available
Prohibits keeping plants for personal use

more restrictive than Colorado
Current Issues in Colorado
and Washington
Regulating the price of taxation
"What if we gave a pot legalization and nobody came?" -Advisor to Washington's marijuana regulators, Mark Kleinman
Legalization Trends
Increase in Accessibility to children
Colorado looking to require child-resistant packaging for edible marijuana products
Vertical integration
: Permitting businesses to get licensed in more than 1 stage of production: growing, processing, or selling
Financial Profits
Ability to Regulate Usage
Free up legal resources
Medical Research
Tax revenues
Industrial/ Commercial Use
Oversee production and regulate sales
Promote safe usage
Of the billions of tax dollars we spent fighting the war on drugs, 2/3rds is spent on police, courts, and prisons. If marijuana is no longer a legal issue, these resources can be used to prevent more pressing safety concerns
Drive the black market out of business
Substance abuse of any kind can cause problems:
- in relationships
- at work
- at school

Less teenagers going to jail for possession/ sale of marijuana
Less pressure from black market dealers to purchase harder, more addictive drugs
Drug disputes on the streets would be significantly reduced
How do the social effects of marijuana differ from those of other commonly abused substances?
The social effects of marijuana are closely linked to the physiological effects that it produces:
- Marijuana use adversely affects cognitive function: (during use as well as a sustained period after consumption)
o problems in sustaining attention
o impaired memory
o affects ability to learn, register, and use information
- Deficits in these abilities make it less likely to develop the proper interpersonal/social skills to do well in school or get a job

Short-term cognitive effects:
- impairs attention and judgment
- causes trouble focusing
- impairs memory and learning

Long term effects
(from chronic abuse):
- can lead to addiction (and subsequent withdrawal symptoms)
- sleep impairment
- may increase risk of anxiety, depression, personality disorders

More research can be conducted on the long-term effects of marijuana
Possibly find more medicinal uses

Legalization and Legislation
The Pros and Cons
Some parties have argued that the aim of the Act was enacted to reduce the hemp industry

Separating Fact from Myth

Because drug use is very sensitive to price and illegality causes the prices of drugs to be higher, the use is lower while marijuana is illegal.
Effects on the heart:
- Increased heart rate and blood pressure (normally 70 to 80 bpm, may increase by 20 to 50 bpm, or may even double in some cases
o These conditions increase risk for heart attack while smoking marijuana

: regulation of the sale, distribution, use, and advertisement of marijuana
Increased Availability
- smoking of any kind can obstruct the supply of oxygen and nutrients to a fetus
- exposure to marijuana prenatally is associated with negative effects on fetal growth and body weight

Statistics on Marijuana Use
United States
Effects on the brain:
Los Angeles
- Impairs cognitive function
o Biochemical basis of marijuana:
The active ingredient, THC, or delta-9-tetrahydrocannabinol, can be absorbed within minutes of smoking/ingesting. THC “disrupts coordination and balance by binding to cannabinoid receptors in the cerebellum and basal ganglia—parts of the brain that regulate balance, posture, coordination and reaction time.
- cognitive deficits detectable at least a week after heavy cannabis use but appear reversible

Medical Marijuana
- the smoke of marijuana, like that of tobacco, consists of a toxic mixture of gases and particulates, many of which are known to be harmful to the lungs
- same respiratory problems
as tobacco smoke:
o daily cough
o phlegm production
o more frequent acute chest illnesses
o greater risk of lung infections and bronchitis

**Although there have been many extensive studies on whether smoking marijuana leads to lung cancer, no definitive link has been established

Medical cannabis is defined as:

1)parts of the herb cannabis used as medicine

2)synthetic forms of cannabinoids

-produces hallucinatory effects
-drug Marinol
-anorexia (loss of appetite) associated with weight loss in patients with AIDS and chemotherapy patients with severe nausea

Cannabidiol (CBD)
- anti-psychotic
-epilepsy, multiple sclerosis spasms, anxiety disorders, bipolar disorder, schizophrenia, nausea, convulsion, inflammation, cancer cell growth.
Still federally illegal under the CSA
Effects on Students

Daily marijuana use correlated with:
- lower grades
- being less likely to graduate
- poorer educational outcome

Leading to problems further down the line:
- lower income
- greater welfare dependence
- lower relationship and life satisfaction
-All three types of treatments are proven to work, but MET and CBT works better than MET alone, and MET, CBT and CM all together seem to work best of all.

-Overall success rates modest.
-Only 50% of enrollees achieve an initial 2-week period of abstinence
-Across studies, 1-year abstinence rates have ranged between 10 and 30%.

-Chronic care model should be used!
