Marijuana can be smoked. The safest way to smoke marijuana is by using a vaporizer. A vaporizer heats marijuana to an exact temperature, which causes THC to evaporate into a gas without burning the plant, thereby releasing less toxic chemicals. Some patients use water pipes, which are also safer than smoking the plant directly. The water pipe filters out some of the impurities that would be inhaled if smoking the plant unfiltered.
