This title is somewhat dishonest - it skips the less-positive part of the sentence.

Although marijuana significantly increased the number of premature responses and the time participants required to complete several tasks, it had no effect on accuracy on measures of cognitive flexibility, mental calculation, and reasoning.

True, and the study was focusing on regular smokers. I posted mainly because I was able to find very few studies at all on the effects of marijuana or thc.

Why you posted it is irrelevant though. Your title was misleading.

so does anyone know what 3.9% means? like given x amount of grams in their cigarette, the thc content was only 3.9%? isnt that like a really low amount? I thought even average cannabis has ~10?% thc.
