Since when is calling someone 'straight edge' an ad hominem attack?
An ad hominem attack is by definition trying to undermine someone's argument by questioning their credibility on the subject. He used 'straight edged' for a "you never tried anything like it so you don't know what you're talking about" angle, so therefore, it is ad hominem.
And since when does wanting to do something you used to enjoy constitute addiction? I assume you avoid EVERYTHING that can be addictive then, since you are so scared of it, right?
No porn, sex, masturbation, gambling, video games, eating, not eating, caffine, driving too fast, any adrenaline-based sport or hobby, shit, people can even become addicted to working out! What a great excuse I now have for not exercising...
Only one of those things you said is a unnatural chemical serving as a physical or mental stimulant. An excess of any given thing can be life-threatening, even water. The difference between those things and ones that unnaturally alter the way your body processes things is that your ability to cut back on such things when they become an excess isn't impaired by the very thing you're doing, and that is an important distinction.
Owyn: On Edit 1, yes, but driving a car is essential to get to work and having sex is essential for producing children (which isn't always a bad thing), while drugs aren't essential towards anything. For the rest of your stuff, fair enough. Contrary to what you might think, I'm in favor of legalizing marijuana, because it should be our choice what enters our bodies and what doesn't, not the government's.
