Marijuana – Get the Facts


Cannabis is at least addictive as alcohol. It is quite different in its effects from alcohol, both immediate and long term, and cannabis is addiction tends to be less obvious than alcohol addiction (alcoholism). However it is just as powerful. Because the cannabis in one smoke can take up to six week to leave the brain ti leaks slowly out of the body, and there are no severe physical withdrawals like shakes or fits. However there are withdrawals like cravings, headaches, tension-states, irritability and difficulty in concentration. The regular pot smoker knows if he/she has a smoke, all these will be relieved. This is addiction.


Length of time in Body:

Alcohol from the wildest binge is out of the body some 48 hours after the last drink. Cannabis can take many weeks from the last dose to leave the body so be aware that the slow withdrawal from cannabis may affect you for months.


Effects of Cannabis on the Brain:

It interferes with learning. Cannabis causes memory problems, in proportion to how much is smoked. The bigger the dose, the greater the loss of functioning. Generally today’s cannabis is much more potent than that grown ten year’s ago. Since it became trendy to smoke pot, countless case studies have shown how school and student performance falls off when regular pot smoking starts.


It interferes with Development of Personality.

If a teenager starts regular pot smoking, even one joint a week his/her personality does not develop normally.  This is because that person always has cannabis in his/her brain. They are not ‘high’ all the time, but the drug is having a subtle but powerful effect in other ways.

They live their life not realising everything is being done under these effects. In particular there is poor memory, reduced attention and concentration (it may be a struggle even to read this pamphlet this far….) a tendency to depressive or even suicidal thoughts, and a turning inside one’s self rather than outwardly to friends. If family and friends are suspicious because of the personality change and enquire, there is a necessity to tell lies about smoking, with later guilt and shame. When schooling suffers, or work deteriorates, there is a tendency to blame ones’ self- when it is really the chronic effects of the drug. The smoker then has a loss of self-esteem, and turns more to the easy ‘high’ that makes him/her feel ‘OK’. So addiction develops further, and the emerging personality is further crippled by drug effects. The harm is now established beyond all doubt, and is merely dose dependent. The bigger the dose, the greater harm occurs. The chronic drug effects also produce an illusion of performance and are very insulating of what is really happening – a sort of mental cottonwool. It cannot be over- emphasised that this is a dose-dependent state; the higher the dose, the more obvious the problem is tho others. Rationalisations, loss of insight and awareness in the user is distorted thinking and denial of the problem.
