Oh yeah I know about heroin... I once had a friend who used heroin and I told him that he should stop or else he'd regret it. Awhile back he died of an overdose. Just keep on going man my advice is find a hobby to do keep yourself occupied and never look back :3

Cannabis isn't either addictive or dangerous. Although they need to stop before they move on to anything harder.

Yeah, I stopped smoking weed a year and a half ago. Weed isn't so much a physical addiction as heroine is, so I wouldn't know, but for me things got alot easier when I found something else to do, that kept my attention. I picked up skateboarding.
