As governments and police forces become more enlightened and realistic, I think we will find cannabis becoming widely decriminalised and eventually legalised in most of the western world within a few more generations. Decriminalisation already exists in parts of Europe and even staid old England has started a decriminalisation experiment in a part of London. Last week a government MP hinted that cannabis would be legalised if Labour get into office again at the next general elections.
The worst, most dangerous and antisocial problem of cannabis is the fact that it is illegal.
A user has to go out in secrecy and 'score', usually from unsavoury characters whom the individual would never normally associate with. Here there is access to more dangerous drugs and more unsavoury characters and attitudes. Ganja heads should never have to mix with drug dealers and gangsters.
A user usually has to mix his expensively bought illicit drug with plenty of nicotine laden tobacco, simply because it is not economically viable to smoke straight herb, unless one is growing lots of it for themselves. Addiction to cannabis is actually addiction to tobacco.
A user (some times in a group) has to take his drug in total secrecy for fear of getting busted. He can't express his ideas and philosophies fully to straight society, without mentioning the profound spiritual, intellectual and creative effects that cannabis has enchanted on his whole being and so he tends not to. Alienation is actually caused by the secrecy and the lack of like minded/experienced people.
Why?
When it comes to illicit drugs, marijuana users usually fall into two camps. In one, only ganja is allowed, in the other, anything goes.
The ganja-only-heads take it because it enhances creativity, imagination, clarity of thought, sex, appetite, relaxation, concentration, wisdom, sleep, dreams etc. (according to ones natural faculties) or it may be for therapeutic and medical reasons. The others take it because it's just another drug to get wasted on! Ok I'm just being a ganja snob, I'm sure that every illicit drug offers something positive to the user. at least for a time, but the long term effects of most other drugs are not entirely healthy.
What I'm trying to say, is that by banning cannabis, governments are criminalising otherwise perfectly ordinary people and depriving them of a massively understudied but profoundly beneficial aid to society as a whole.
The general drug users/abusers won't stop whether cannabis is legal or not, so why keep the sheep in the wolves pen?
