Hi, stiltz. No, it is not a mad idea and if you find a way to participate please let us know of how it helps.
The hype about cannabis has driven the usage of the plant 'underground' and created a ridiculous neurosis about it. It is a plant that has mind-boggling potential but its illegal status has been driven by international politics that has nothing to do with its so-called dangers.
One of the issues that is problematic about the culture of illicit use is that it heightens its evident attraction to young people, who are drawn to using it more so because of the rebellious-seeming nature of its use as well as the fact that it feels good. And therein lies the problem for those people who ban it - yet probably use it themselves; it feels very nice. But cannabis use in young brains is dangerous since brains do not finish developing until around the age of 25 and are extremely susceptible to its effects. Another problem is that young people are developing skills of survival in this increasingly hostile world, and often feel distressed. To bypass the learning curve from handling these feelings by using cannabis is unhealthy. But its judicial use, like that of alcohol, can be pleasant.
There are other issues around its illicit status, such as the creation of a criminal subculture of ordinary people, as well as the creation of very rich drug lords. But its unfettered use is also problematic - but none of this can be openly discussed whilst the public have been whipped into such an ignorant frenzy about its use at all.
The only way to begin to gain some control of its use and to stop the real madness - the illicit use of stronger and more potent strains and the criminalisation of people who are caught using cannabis, is to legislate its use. A bit like alcohol and prohibition, I guess. But there is no political will to do that - too dodgy in the eyes of the electorate, so poorly people will have to toe the pharmaceutico-medical line.
There is no doubt whatsoever that cannabis and its derivatives will be more freely used some time in the future - probably very a needlesome prospect for Big Pharma, who could never control it and who, it would never surprise me, have a vested interest in keeping its use illegal. So no, stiltz, you are not mad. The fact that you even ask that question is a sign of the madness of the hype around cannabis and the madness of how the masses are manipulated into thinking what powerful legislators want the masses to think. You must be very poorly for your son to have sent this to him. The only harm you might incur would be to face a legal problem, but I wouldn't know about CBD; it looks really interesting, so thanks for bringing it to at least my attention.
Good luck be yours.
