Currently in Canada, the public has access to Cannabis for medical purposes through regulation by the ACMPR.
Cannabis effects the nervous system in a variety of ways depending upon the person. For some people it speeds things up and they get 'high'. For others, it slows things down and they get 'low'. For some people it causes complete body paralysis. For others, it may have little effect or just cause a headache.
For people who suffer from depression but whose bodies respond to cannibus with an increase in the nervous system's activity, cannabis acts as a stimulus and may relieve their symptoms. For some others, who may suffer from an over excited normal state, for example, in the case of epilepsy or painful muscle disorders, if cannabis acts as depressant and reduces the nervous system's activity, then that person may also have reduced symptoms with cannabis use. The reality is that cannabis only has a positive affect if the use of cannabis helps stabilize a nervous system that is 'out of whack'. For the rest, altering the state of the nervous system causes stress that overtime can lead to future disability and ill health.
Because cannabis has been illegal, the current body of research is incomplete leaving the public as well as the medical community with many questions. One thing for sure, however, is that cannabis does affect the functioning of the nervous system. And according to users, smoking cannabis is the most effective way of administering the mixture of naturally occurring chemicals that cause the positive neurological effects felt by patients who use cannabis for medical purposes.
This is where the problem arises, smoking cannabis releases this very potent cocktail of chemicals along with other hazardous chemicals into the air and unless your body will benefit from exposure, exposure will have a non positive drugging effect on your nervous system. Your nervous system will be taken from a state of 'balance' to a state of 'imbalance'.
Being exposed to these chemicals happens even when you stand beside someone who is not smoking but who is wearing contaminated clothing, when you walk though the smoke released when someone smokes outside, and even when you enter a space where smoking had occurred in the past. If you are breathing it in, you are taking in drugs. Even the plants themselves, off gas these drugs when growing. Some people will notice an effect in these cases, but others will not.
THC and its derivatives, form the most predominant chemical group found in cannabis. These chemicals are sticky, fat soluble hydrophobic molecules for the most part. The chemistry of these molecules is one of the barriers for administration in a cold pill format and likely contributes to the overall patient complaint that pills do not work as well as smoking. Most would agree, hot oil flows freely, it is higher in energy, and is easier for the body to process. A hot burger tastes better then a cold one for sure and heating up cannabis makes it easier for the body to absorb the fat soluble chemical that provides a medical benefit for patients.
That being said, the rest of the people who do not benefit from exposure, should not be exposed to cannabis. It has powerful drugging effects on the nervous system of most people and should be strictly regulated to protect the public.
Cannabis does not produce candy. It is a powerful organic machine that produces a vast array of little understood chemicals that can alter the nervous systems of mammals. Hopefully, with the right research, the nature of these chemicals will be better explored and new safer effective ways of administering these chemicals as medicines to patients in need will be discovered.
