I've seen a lot of various substances and supplements suggested around the forum recently for lucid dream induction. Some seem harmless, others seem like they could be rather harmful. I'm curious what everybody's take on these methods versus the mental methods of induction, such as MILD, WILD, and the like.

I prefer to use the mental methods. The main reason for this is that I like to do things myself, and rely as little as possible on outside methods. If something I rely on suddenly fails or stops working for me, I'd much rather have it be something I can influence directly than go to other about. Also, I don't like the idea of using various substances on my body. In addition to the potential negative effects of whatever I might use, there's also the issue that the body maintains a certain chemical balance. If we do something to change this, the body will change its chemistry slightly to compensate, and eventually the substances will reduce in effect, and we will develop a dependence on them. Not something I want to deal with.
