Noticeable differences in effect stem mainly from the relative mix of male and female plants--the female plant being more potent.
To differentiate their products some pushers use a "hype," a process that entails dusting the grass with extracted THC. The pushers then tell their customers the plant itself is a higher quality, Walters said.
To cut costs, some drug distributors switched to lacing the drug with synthetic THC and are now apparently using PCP, reactions to which are very unpredictable.
John Day, senior tutor of Dunster House, said Thursday that no serious drug problems have been brought to his attention this school year, but that last year he had at least one serious case.
Epps said that so far this year no student has been disciplined for selling drugs on campus and that Davis and Walters agree the lab-manufactured drugs are probably not synthesized at Harvard.
Epps said he feels it important for students to realize they can go to UHS and receive medical help and counseling on a strictly confidential basis. The administration has no interest in learning who the students are who have problems with drugs except to help them, he added
