For better or worse I know a lot of people who smoke methamphetamine. Never smoked it myself and never would. Most of them smoke it recreationally without it causing any problems in their life or addiction. They have no issues when they're not smoking it, they can stop when they want, and they don't let it negatively affect the rest of their life (work, relationships, etc.). Some of them are weekly smokers, some of them are only once or twice a year. But around 10-20% of the people I know who smoke it have issues with dependence and addiction, and it's caused massive problems for them (and those around them) and for some of them it's destroyed their life. I don't know anyone who uses heroin, but I'd imagine that it's the same. "Hard drugs" are surprisingly non-addictive, less addictive than nicotine and probably even less addictive than caffeine. The reason why these drugs are "hard" though is that if people do develop an addiction, it's so incredibly destructive. It becomes their life, everything they do becomes drug-seeking behaviour. They don't even like the drug any more, but they need to keep doing it just to feel normal.
