^ You can disagree all you like but doesn't alter the fact that no such distinction exists as there's never been a definition of what those terms could really mean. Your definition doesn't work cos all drugs can be taken in both ways you suggest. In fact 'hard' drugs (in the media sense - heroin, coke, meth and so on) can all be used for days on end without problem. It's all about dosing and tolerance in that case. You can drink booze day in, day out and never be found out at work too apparently. Other people need to call in sick cos they had an extra shandy the night before. This is why it is a meaningless distinction - totally depends on the individual.
For instance, if I smoke weed all night I'm wrecked the next day and would be shite at work. If I take heroin all night I'm fresh as a daisy. Does that mean weed is a hard drug and heroin a soft drug? Does by your definition. See the problem?
Can be chased off tinfoil but gives off
vast plumes of smoke so you need reasonably decent technique not to waste loads. Or have loads to waste in the first place I suppose. Other than that it can be eaten (or made into tea I suppose) but tricky to work out doses. I'd chase it if It were me. Or you could always make a pipe or bong out of bottles, pipes, cans and so forth.
Also, lucky you - I fukkin

opium resin. What type do you have? Usually either looks like hash (opaque, sometimes with lii bits of 'straw' in it) or looks like brown bottle glass. The latter is the Good Stuff %)
(the former ain't exactly shit, mind)
