There is probably no approach in the CR to stop a pothead from continuing to use, abuse, and push smoking marijuana. The purpose in responding to disagree is to insure that the readers here are not bulldozed by the erroneous information that is common to users of cannabis, who, understandably, wish to believe that their abuse of mind altering substances is actually healthy. In the addiction field, that is known as denial, though that particular defense mechanism is a chameleon, presenting itself in many colors.
THC, the main mind altering ingredient of marijuana is neither a sedative (though it has such a side effect), not stimulant. Rather, it is hallucinogenic. Generally, such effect is experienced only when used in high volume, and it is not experienced after a single joint or blunt. Regardless, it has known and documented toxicity (fancy word for poisoning) in smaller amounts, and has long term damaging effects on many organ systems. It lacks the drama of overdose common to many other drugs, but is no less dangerous and toxic. The effect of most other drugs is limited, as they are water soluble, are metabolized in several hours, and are absent from the body within several days. Not true for cannabis. A single joint of MJ is still detected in drug screening a week later, and regular use guarantees the detection for up to 6-8 weeks. THC is absorbed in cell nuclei, and the damage can continue weeks after last use. THC has profound effects on many parts of the body. Brain damage, impairment of all glands and glandular systems (thyroid, pituitary, adrenal, reproductive, etc.) are all documented, and are not uncommon. When used as “medical marijuana”, it is much like medications that each has its benefits and risks, and are applied by a medical professional who weighs these and reaches an educated conclusion.
Marijuana is not benign, and it is misleading to consider it safe. It should be illegal in all forms, and should not even be treated differently from the other “more serious” drugs. Use of makes people dumb and stupid, hence the justifications that are inconsistent with scientific fact. It makes its users lazy, killing motivation to do anything. My personal preference when I wish to be lazy is to do it without chemical inducement. Thus I am no longer impaired when I choose to get up and return to action.
