Hallucinogen sketches 1969-71

In the first two years of my Diploma course I continued to draw under the influence of hallucinogens occasionally. I used some of the images in my print making course during the first year. I have since lost some of these sketch pads, stolen when my house was squatted while I was away in the USA, but these are from a couple I still have. After a while I was getting no fresh insights so I stopped doing it.
