I usually don't like people who label themselves as "straight edge". I know they aren't all the same, but most of them are so judgmental. I don't see the problem with partaking in alcohol, marijuana, or cigarettes, or not partaking in these activities.
It's a very small percent of people who drink alcohol or smoke marijuana that get addicted (and you can only be mentally addicted to marijuana). Even those who do aren't usually bad people anyway and already had other mental issues that leads to addiction.
As I said earlier, I have no problem with people who don't partake in drinking or drugs. That would be stupid if I did. I just can't stand the pretentious attitude so many people seem to have that label themselves as "straight edge". I don't see the need to label yourself as that anyway. I don't run around with a shirt on that says "I drink!" on it.
