"As demand for marijuana-based medications accelerated, pharmaceutical firms attempted to produce consistently potent and reliable drugs from hemp. By the 1930s at least two American companies – Parke-Davis and Eli Lily – were selling standardized extracts of marijuana for use as an analgesic, an antispasmodic and sedative. Another manufacturer, Grimault & Company, marketed marijuana cigarettes as a remedy for asthma."

The human body produces its own cannabis-like compounds, called endocannabinoids, that react with the body’s cannabinoid receptors.
Cannabinoid receptors in the brain stem and spinal cord play a role in pain control, vomiting reflex, appetite, emotional responses, motor skills, and memory formation.
THC and the Developing Body
24
"Twenty-eight years after discovering THC, in 1992, Dr. Mechoulam, along with Dr. William Devane and Dr. Lumir Hanus, identified the brain's first endogenous cannabinoid (or endocannabinoid) - the brain's natural version of THC -which they called 'anandamide,' from the Sanskrit word 'ananda,' which means 'eternal bliss' or 'supreme joy.' Vigorous exercise stimulates the release of anandamide, and the sense of euphoric well-being that comes with a healthy workout - what jogging enthusiasts refer to as a 'runner's high' - is due to elevated levels of endocannabinoids. The endocannabinoid system in the brain is also believed to help mediate emotions, consolidate memory, and coordinate movement."
Controlled Substances Act
� Controlled Substances Act as having a “currently accepted medical use in treatment in the United States,” must meet a five-part test:
(1) The drug’s chemistry must be known and reproducible, (2) there must be adequate safety studies, (3) there must be adequate and well-controlled studies proving efficacy, (4) the drug must be accepted by qualified experts, and (5) the scientific evidence must be widely available.
� According to the DEA, botanical marijuana meets none of these
requirements. First, marijuana’s chemistry is neither fully known nor reproducible. Second, adequate safety studies have not been done. Third, there are no adequate, well-controlled scientific studies proving marijuana is effective for any medical condition. Fourth, marijuana is not accepted by even a significant minority of experts qualified to evaluate drugs. Fifth, published scientific evidence concluding that marijuana is safe and effective for use in humans does not exist

Dab From Farming to Chemistry
Potency
� Concentrates : 710 is the new 420 � Butane-extracted hash oil (BHO)
A chunk of the stuff the size of a Tic Tac can be the equivalent of hoovering up an entire joint in one
massive toke. Even for hardcore smokers, the experience – which fans call dabbing – can be like getting high for the very first time. Your head spins,
your eyes get fluttery, a few beads of sweat surface on your forehead and, suddenly, you're cosmically
baked.” (Rolling Stone Magazine, 6/20/2013)

Intoxication
A. Recent use of cannabis B. Clinically significant problematic behavioral or psychological
changes (e.g., impaired motor coordination, euphoria, anxiety, sensation of slowed time, impaired judgment, social withdrawal) that developed during, or shortly after, cannabis use
C. At least 2 of the following signs, developing within 2 hours of cannabis use: • Conjunctival injection • Increased appetite • Dry mouth • Tachycardia
D. Symptoms not due to a general medical condition and not better accounted for by another mental disorder, including intoxication with another substance
68
Withdrawal A. Cessation of cannabis use that has been heavy and prolonged (ie, usually
daily or almost daily use over a period of at least a few months). B. Three or more of the following signs and symptoms develop within
approximately 1 week after cessation of heavy, prolonged use: • Irritability, anger or aggression • Nervousness or anxiety • Sleep difficulty (ie, insomnia, disturbing dreams) • Decreased appetite or weight loss • Restlessness • Depressed mood • At least one of the following physical symptoms causing significant discomfort:
abdominal pain, shakiness/tremors, sweating, fever, chills, or headache
C. The signs or symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
D. The signs or symptoms are not attributable to another medical condition and are not better explained by another mental disorder, including intoxication or withdrawal from another substance.
It’s addictive
Adults users are more anxious,
more psychotic, less alert, more
disorganized, have dry mouth,
and are more hypertensive and
want to use more.
1 in 10 adults…
1 in 6 adolescents…who try marijuana
will become addicted More adolescents are using
marijuana than smoking
tobacco

Toxiology
absorbed into body tissues (including the brain, heart, and fat) or transformed by the liver
Because THC is stored in fatty tissues, it accumulates faster than it can be eliminated in chronic repetitive smokers. Leads to extended retention of THC which is then eliminated from the body at a relatively constant rate with an average elimination half-life being estimated at 18-30 hours.
Urinary results difficult to interpret due to variables such as dosage of THC ingested, frequency of use, timing of urine collection relative to last exposure to marijuana, rate of release of stored cannabinoids in adipose tissue, and an individual's hydration state.
Substance Use Disorder (Addiction) 1. Taking the substance in larger amounts or for longer than the you
meant to 2. Wanting to cut down or stop using the substance but not
managing to 3. Spending a lot of time getting, using, or recovering from use of the
substance 4. Cravings and urges to use the substance 5. Not managing to do what you should at work, home or school,
because of substance use 6. Continuing to use, even when it causes problems in relationships 7. Giving up important social, occupational or recreational activities
because of substance use 8. Using substances again and again, even when it puts the you in
danger 9. Continuing to use, even when the you know you have a physical or
psychological problem that could have been caused or made worse by the substance
10. Needing more of the substance to get the effect you want (tolerance)
11. Development of withdrawal symptoms, which can be relieved by taking more of the substance.

� May cause excessive sedation when combined with perioperative medications. Avoid marijuana if scheduled for surgery in the next 2 weeks.
� May increase the risk of bleeding when used with aspirin, anticoagulants, antiplatelet drugs, nonsteroidal anti-inflammatory drugs, and ginko biloba
� May affect blood sugar; medications for diabetes many need to be adjusted (e.g. metformin or insulin). Use caution if taking herbs and supplements that affect blood sugar.
� May lower blood pressure. Use caution with medications, herbs or supplements that lower blood pressure,
� May increase drowsiness when used with benzodiazepines, barbiturates, narcotics, some antidepressants, and alcohol.
� Affects the liver’s cytochrome P450 enzyme system (CYP450) and could result in increased blood levels of medications metabolized by CP450 leading to adverse reactions.
