^^That's a matter of opinion. I'd say, for the most part, no it's not worth it. Using heroin is not really an experience that you take anything meaningful from, like you might experience with certain other substances...psychedelics, marijuana etc. It's a great high while you're on it, but it kind of just turns your whole life into a blur when you're using it daily for a long time. It's a full time commitment, that's for sure!
Are you considering using Heroin?! I would advise against it, particularly if you're inexperienced with opiates. Any opiate can be highly addictive, but if you want to feel what heroin feels like and you have no tolerance to opiates, there's much safer, easier alternatives than heroin that will pretty much give you the same high. However, if you have an addictive personality, any opiate is probably a bad idea, IMO.
There's plenty of movies/books/blogs etc. that pretty accurately portray the life of a junky. Hell, this whole site is loaded with info about it. Check out the heroin discussions in some of the other forums, you can sit there and read about junkies for days!
It's possible to hide an H addiction and function normally, as long as you can support your habit with your income. Yet this lasts only so long, your tolerance will grow to the point where you spend all you earn just to keep well, and beyond that. Sooner or later family, friends or coworkers will also catch on, and you'll likely loose your job and your means for maintaining and leading a "normal" life along with it.
Also, you'd need very reliable suppliers, for the reasons above, you simply can't afford getting sick or wasting too much time looking for stuff.
So, depending on how good you are at hiding and keeping your tolerance in check, it may work for months up to several years, but ultimately you'll have to pay the piper.

I agree 100i%....I might write a blog about what my daily routine was....I held a job for years and maintained a hefty dope habit for both me and my girlfriend, and it all did come crashing down. I lost my job,,LZMmy car, everything....There I was faced with the decision of commiting serious crimes everyday or detoxing and goingpthrough rehab, I had no choice....It just gets so fucking expensive!!
Heroin kills your sex drive, especially for guys
