Off the record - there are many other and much more rewarding ways to get in touch with music than to simply take drugs.
Of course! Like meeting idols and favourite interpreters and finding out stuff you really didn't know before, that video of Stephen Hough being a great example.
I agree with points being made that alcohol is often enjoyed for the taste rather than for the effect it gives, while anything illicit is used simply for the high. This, to me, says a lot about the character of the users in question.
I disagree. The situation with alcohol regarding those that enjoy the taste (like at wine tasters) and those that drink it to get drunk is exactly the same with cannabis, but I agree with you about other hard drugs. I doubt you'd find a heroin addict connoisseur

.
The thing about cannabis is that there are many connoisseurs who are always looking for different tasting and different smelling strains, and many smoke marijuana because it tastes nice. The high is simply a result they don't mind, much like with wine testers that don't spit it out after tasting it. I think of myself as a little bit of a connoisseur. I once bought some that gave me a headache and made me quite nauseous every time I smoked it (which I think was because it wasn't cured or flushed properly, a step that many dealers miss out simply because it takes time and they need a quick sale), and I've been cautious ever since.
But I do agree with you on the character of the users who simply use it to get high. I usually differentiate between those that smoke weed to get high and those that smoke it for taste and other reasons by the way they smoke it. There are those that smoke it through a bong or pipe and there are those that smoke it through joints and vaporisers. Those that smoke it through joints are (from my experience, where rolling is an art form) more keen on the joint itself than what's inside it. Sometimes I even see these people (including myself) rolling joints without any weed inside, just to practise the skill and discover new methods and techniques. These characters are often also users of vaporisers, as they care about the damaging effects of cannabis and like to reduce them as much as possible. Then there are those that smoke it through bongs and pipes exclusively: these people are the people that only smoke weed to get high; and as that's their primary motive, they use bongs and pipes because it's quicker and doesn't require excess materials like making joints does (tobacco, skins, roach etc).
As I said before, these people are the type that will most likely do the same with other drugs, and the kind that can sometimes discredit marijuana. I myself enjoy the act of rolling so much that sometimes I think about not smoking it after rolling it, and I sometimes take the insides out and do it again! Last night, whilst at a friends finishing off the remainder of some that I had before school started, I had the idea to rip off the sticky gum part of these strawberry flavour skins I had and twist it around the joint which was rolled with plain skins. The result was a joint with a strawberry pattern twirled around the edge, and which also tasted of strawberries every so often.

One night out a while back saw two stoned men pinning me up against a wall waving a knife in front of my face.
Oh my god! What happened? Did they mug you? Did they cut you or anything with the knife??? My god, I've never heard a stoned person go that far! But I'm glad you realise that it's the user and not the drug. Still, what a frightening ordeal!
The reason Cannabis is illegal and alchohol is not is a social factor. Society says it is ok for people to drink, but not to smoke pot. And as people increasingly view smoking as something bad its becoming less and less the norm to smoke.
I think that's due to the sheer amount of lies we've been fed about cannabis, and a topic I linked to earlier shows this. It was about this man billing for cannabis to be criminalised, and his reasons were wholly untrue. One of them was: "You smoke a joint and you're likely to kill your brother." Back then, this would be taken as gospel truth; but nowadays, thankfully, we have many studies being undertaken that are finally proving the real facts about cannabis.
