I just stumbled on this through an artist friend on FB. The link below will take you to an online gallery of self-portraits that Bryan Lewis Saunders painted while under the influence of various licit and illicit drugs.
I think these self-portraits provide some insight into how one is affected by the various drugs. Some drugs seem to have absolutely crazy effects on how one views oneself (esp. Bath Salts and PCP), while others appear to be very calming.
How much can be gleaned from these self-portraits is obviously up for debate, and clearly different people will react differently... but I find the portrait series (which he has been painting for something like two decades) very interesting and thought my fellow DC's might too.
