This article treats LSD on a superficial level, and brings out solely its negative effects. It is clear that the writer is against its use, but a more convincing argument would include a discussion of its positive benefits as well. For example, LSD can greatly facillitate emotional release, deeper insights into the nature of reality and one's own mind, which, if applied by its user in his/her daily life, could lead to personal growth and psychospiritual maturation.

I've never seen anybody addicted to LSD. What I've consistently seen is people quitting drugs entirely after taking LSD. Moreover, I've never heard of anyone dying from LSD
