first you say that the desert analogy is a good one, then you say it is ridiculous. The difference, people don't order themselves 2,3,4, deserts after a meal, but drug doses DO increase over time.

What I have not consumed myself I HAVE witnessed others consuming.
It usually becomes the number one agenda, usually becomes a daily occurence, and as time goes on, the day gets planned around it's use.

I find all of those characteristics proof that the drug takes over the person. That is what I don't like about drug use. It robs the person from your life, and unless you partake in the drugs, the drugs become more important to the person than your friendship.
