"Smoking a lot affects the way you act," she says. "Your mentality changes when you smoke up a lot; you're used to being high."

Recounting her own experiences with marijuana, she attributes this decreased acuity to feeling high.

"You definitely feel more relaxed [and] everything's definitely more hazy," she says. "You don't have clear thoughts and it's harder for you to speak sometimes.

The student, who considers herself a former occasional smoker, says inhaling marijuana also can impair one's control.

"I have driven while I was high and it definitely does [have an effect]," she says. "You don't have as much control; your ability to register things is much lower."

Another smoker--a sophomore in DeWolfe--says heavy marijuana users do not speak coherently.

"You can tell people who are on it from their speech patterns and what they say," she says. "If they smoke a lot, they talk slower. It's just like they're really mellow all the time."

The student--who says she smoked marijuana for the first time last year with acquaintances who lived in Quincy House--says watching heavy smokers convinced her to inhale only nine times.

"I didn't want to become a pot head like my friends," she says. "Ten and up is just a problem, you start losing track [of how much you've smoked]."
