guinea pigs for this experiment. Scientists expect the answer to |
be yes. |
Affects behavioural mood and memory functions. Decreases cerebral |
blood flow while smoking. |
Of students failing or leaving school, 1/25 were not pot |
users, 3/5 of students regularly smoking pot failed. |
Flight simulator and pilors after 1 cigarette...each pilot |
did significantly worse with one pilot missing the runway. |
Significantly, all pilots thought they were doing very well. |
The single greatest risk factor for cocaine abuse is |
marijuana use before age 15. |
1. Loss of interest, apathy, desire to work |
2. Fatigue, loss of energy/tiredness |
3. Depression/attacks of rage when provoked |
4. Slovenliness in habits and appearance |
For chronic users, clearly has been shown that memory tests and |
auditory and visual retention tests were poorly done even after 6 |
weeks of sobriety. |
In a study of alcohol/pot related accidents, suggested pot may be |
responsible for more accidents than alcohol (due to impaired |
judgement etc) |
In a number of cases, heavy use 4-5x a week up to 15 cigarettes |
per cay caused amnesia for the first 7-8 days of sobriety. |
Amnesia was not recognized by the user. |
Sheba=PCP added. Smells like embalming fluid |
Few drops of vinegar in urine will give negative marijuana test |
Drug screen 50-75 level CANNOT BE PASSIVE. No false positives. It |
is like a fingerprint. In a job screen should always do a |
confirmation titer if a screen is positive. |
421 chemicals. 65 are different cannabinols which are |
psychoactive (delta-nine most) Others include non-cannabinols |
such as toxins, carcinogens (such as tar, just like the tar on the |
road) and inactive or potentiating agents |
Alcohol takes 6-8 hours to get out of body |
THC is fat-soluble, and 50% will be in the body 1-2 weeks later. |
May take up to 4 months to get all out. Heavy use for 6-12 months |
will give positive drug screen 4-6 weeks later. |
A chronic pot user is raraly sober. Subclinical |
intoxication. 2-3 times a week sufficient for this. Level |
released from fat as acute level drops. Stored in all fat and |
also in the basic building cells of the body. |
Damage is DOSE RELATED. Depends on frequency and on |
concentration. The more mature the person the less permanent |
damage. Symptoms are insidious and subtle and can parallel |
adolescent adjustment symptoms. THC exaggerates these symptoms, |
makes them more profound and often permanent. Saturation in the |
brain causes memory impairment, concentration impairment and |
motivation impairment. Can be a major personality change. As the |
brain level decreased THC moves from other body fat to the brain |
to keep the brain saturated. Can actually prevent the cognitive |
changes needed for an adolescent to change to an adult, leaving |
him/her with poor social judgement, poor attention span, confusion |
and anxiety and loss of train of thought. Occasionally produces |
hyperactive/aggressive/agitated person instead of apathy. This |
damage can occur in MONTHS rather than years. ALL USERS |
TO THEIR POTENTIAL ABILITY. Regression to immaturity can occur |
and can be irreversible. A teenager can develop, for example, a |
mental age of 11 and thus not be able to complete school work |
causing a dropout from school. |
Pot more potent than in past years, age of onset much earlier |
and thus the profile of a marijuana user is changing. |
a) much higher suicidal ideation and depression |
b) 1/3 show borderline schizophrenia traits with disorganized |
thought patterns. |
c) Paranoia increasing |
d) Lots of similarities to a senile adult. Difference in time |
perception (10 minutes seems like 1 hour). Erratic junk foods. |
Poor judgement. Cannot self-correct. Much like Altzheimer's |
e) As use continues with subacute intoxication, decreasing |
cognitive ability, decline in emotional life, much increase in |
stubbornness. More fatigue, decreased ability to do complex |
tasks, no self-insight, no idea of time and dates, impaired short- |
term meory and occasionally long-term as well. With Moderate dose |
get profound gross impairment of motor skills. (See how much like |
brain-damaged adult?) With high dose can get hallucinations. |
Feel that THC may be the cause of massive adolescent psychiatric |
problems. MUCH PROOF HERE and much refusal of the user to take |
this information seriously...still relying on the information from |
the 1960s that THC was not harmful. User does not wish to look |
the data straight in the eyes. |
Major driving impairments..."behavioural toxicity". The |
stoned person does not perceive the dangers. He can briefly hide |
the influence and pay attention but easily loses focus. Coming |
down from a high may be the worst for motor skills. Occasionally |
get a triggered unexpected after-high. |
39% more likely to have a driving accident if smoke THC and |
drive. Reckless driving, failure to yield, failure to stop. |
How to tell if the memory/behavior is THC? STOP for two |
months and see if symptoms go away. |
1. First stage is exposure. |
2. Second stage...the person learns the mood swing, starts to use |
it as a drug and seek it and plan for its use = second stage of |
3. Third stage..user becomes preoccupied with the mood swing. |
Develops tolerance. May use 3-4 x per day up to 15 per day = much |
increased tolerance. Develops a preoccupied with chemical |
dependence life style. |
4. In the fourth stage the addict is using the drug to be NORMAL. |
Uses first in the AM, last at night, using it just to function. |
*Stages three and four...the patient usually cannot stop on his |
own but needs a formal treatment program. |
