Q: I sometimes smoke pot on the weekend. Can this affect my work during the week?
A: It sure can. Although the immediate effects typically last only one to three hours, frequent users can have a hard time concentrating and processing information, even days later.
Marijuana has other risks, too: It contains more carcinogens than tobacco and can cause the same respiratory issuespossibly even cancer. Bottom line: Your weekend habit could have consequences way worse than just making you feel spaced out at work.
