Weed in the 70's was similar in quality as it is today, in the usa you had green home grown looking stuff and commercial mexican or you had columbian hightest(some reds and golds were stupendous) or thai sticks. Lip is right some of what is available today is maybe 2X if that. It has to because of the genetic control available today. Hash was much better we used to able to get lebonese, afghani & nepalese of any color. 2 hits and you out to the 2nd degree because thats all tour lungs could take.
