If you do heroin, only way to do it is to shoot it.
That said, doesn't really matter. If you enjoi heroin, you should definitely shoot it.
Just don't get strung out man. Easier said than done, but it really ruins alot of people's lives. On the other hand, seeing so many people who did heroin with me really motivated me to go to college and do good and be an upstanding citizen in life and become active with politics. I mean, I saw so many junkies ruin their lives and go to jail over drugs. It really moved me inside, and was a big factor in making me so determined to never be like that, and really make something of myself.
I mean, I remember the first time I went to baltimore to get heroin. I had got it locally once, where it came around once and only once. I decided to contact someone from Bluelight and within 2 hours I was going to meet someone for the first time and buy some dope. It all worked out, but I just remember I had just turned 16 and was shooting in the guy's house. He had another friend over who had been snorting it for years, and said he was never gonna shoot it.
Then he sees me, this 16 year old little kid, and he says fuck that and decides to shoot up. It's been particularly interesting for me to chronicle how my life has gone, compared to his. Although I had shot up heroin ~20 times since buying a gram locally 2 months ago, it was my first time really establishing a connection to the heroin world, and it was his first time shooting up. Since then, he's lost his $120,000/yr job, lost his Audi and his other cars, his beautiful down-town apartment in Baltimore, and been to rehab more times than you could count and now lives with his parents. I, on the other hand, have never been to rehab or been strung out, and doing great in college. It kinda blows my mind how me and him have gone so differently in our lives.
So just be careful. Do what you do, there's no 'invisible line' or anything like that at all. But some people can't handle doing heroin and are extremely irresponsible. Just be careful, I'm not saying don't do it, but make sure you keep your priorities straight, as is the case if you didn't use too.
However, let me point this out: Nothing good can come from doing anything illegal. If you are busted, you are ruined. Take note that people who are 'straight-edge' have just as happy and fulfilling lives, if not more so. To anyone who's done drugs, you are stupid if you think it was better that you did drugs. I'm not saying it's worse, but everyone has a number.
