I agree with Rand on some points, and I disagree on others. Agreeing with someone and referring to someone for their knowledge does not keep one from thinking for themselves. Much like writing a paper you may consult many sources in order to come to make your thesis and come to a well thought out conclusion, but it takes a great deal of thought to bring a well thought out argument together.
About the drugs: If in 'drugs' you include everything from nicotine and caffeine to heroin and shrooms, then no not all of them imply the desire to escape reality. My main disagreement was with the idea that shrooms, which Liriodendron Tulipifera earlier only described as being used to hallucinate (mildly to greatly depending on dosage), are somehow not an escape from reality. While I have never done them nor plan to, those who I know that have all knew and openly admitted that the purpose was to hallucinate. If that is the purpose, I would definitely say they have a desire to escape reality.
