Workplace drug policies promote the use of coke???
Because you can use coke at the weekend and pass a drug test nae bother on the Monday morning.
Smoke a joint or two at the weekend, and whilst you might be stoned, umm sorry, stone cold sober on Monday morning you'll fail a typical workplace drug test, and you'll still fail on Friday. If you don't smoke anything for two or three weeks you should generally, though there's no guarantee,by then be OK.
And of course it is a policy that works on the basis of guilty until proven innocent.
Whether you want to believe it or not, if cannabis or whatever drug for that matter gets legalized, street dealers will offer "better for cheaper". Simple competition, you'd be playing right into their hands, they won't just stop selling on the side because there are now legal places selling it.
I think the USA’s prohibition experience suggests otherwise. Though obviously, as we have found with tobacco, if the legal price is stupid high then people will turn to other sources.
The other thing that has happened, as a result of most western countries outlawing cannabis, is there is no control over the development of the drug. Genetically modified skunk can be a completely different beast to natural organic cannabis.
The war on drugs continues to work against all. Whilst of course most people are completely in denial of the dangers and massive social impact of alcohol.
Ain’t we a bit off topic here?
