Opiates are types of drugs that have been used for many years to treat pain.
Studies indicate that most of the damage caused by most drugs will eventually heal when the individual stops using them; this is not the case with the abuse of inhalants.
The depression so many Ecstasy users complain of after coming down off of the drug is often referred to as the Tuesday Blues or Suicide Tuesday, because of the midweek depression that users often experience after having used the drug on the weekend.
Physical changes associated with methadone are similar to other opiates and may include a suppressed cough reflex, drowsiness, and constipation.
