If you take heroin or cocaine or smoke weed will you sleep at night?

I know people who have taken these substances. You may sleep at first. However, over time, you won't sleep and you will have mental problems. Requiring counseling and med.'s. If you don't die first. Some of these people can't even lift their heads up. Also, over time, the drugs can lose effect and you may still be addicted. It's really a lose, lose situation. If you don't believe me. Call a professional counselor or mental hospital or a police station. These people deal with this every day.
