Some people smoke marijuana because they claim it releases their inhibitions.
Unfortunately, this isn't always a good thing. By releasing a person's inhibitions, marijuana could cause the user to make poor judgments and bad decisions. Sometimes, inhibitions are a good and necessary thing in life. The decision to have sex is a big step in life, and if you don't think carefully about all the consequences and important factors before having sex, you may end up regretting your decision for the rest of your life. When you're high, you may not think about the consequences of having sex and may be more likely to have unprotected sex.
