in the early 70's I was working in the middle east and got some Lebanese Blonde hashish- we were smoking from a mersham pipe- not sure of speliing here- it had a face carved upon it- as my friend was handing the pipe to me the face on the bowl grinned at me- yes I have had hullicinations from smoking- this was the most visual experience I have had though- 35 years ago and I still remember it
