DOPE smokers are trading sexual highs for the chemical kind.

That's the conclusion of Marian Pitts and her team at La Trobe University in Melbourne, Australia, who studied the results of a 2005 phone survey of 8656 men and women aged 16 to 64.

Men using marijuana were twice as likely as non-users to have had two or more sexual partners in the previous year. However, men who smoked marijuana daily were four times as likely to report having trouble reaching orgasm as men who didn't use dope.

Some had the opposite problem. Smokers were three times as likely to experience premature ejaculation as non-smokers (The Journal of Sexual Medicine, DOI: 10.1111/j.1743-6109.2009.01453.x).
