There is nothing 'good' about heroin in any form.

Although I think that if you want to try drugs then you should I draw the line at heroin or injected speed.
While some weed or speed might give you a buzz and make you feel good about yourself and the world around you nothing that you ever shoot into your vein can do any good for you.
All that will happen is you will enter a cycle of addiction from which the best outcome would probably be a quick, painless death (as opposed to months or years of torture, loss, etc).

And yeah, I know that that sort of stuff can happen with non-intravenus drugs but it is far easier with needles.
