Naturally occurring sources refers to psychoactive chemicals or their precursors that already exist in nature. This is in contrast to synthetic psychoactive compounds which are artificially produced or designed in laboratories. An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids , whose acidity is associated with their carboxyl group –COOH. Sulfonic acids , containing the group –SO 2 OH, are relatively stronger acids.
