"There's a big difference between somebody who does acid on weekends and somebody who takes downers every day"

This quote by Tommy Rettig is referring to the distinction in between leisure substance abuse and substance abuse. Taking acid on weekends indicates that the individual is using the drug recreationally, while taking downers every day suggests that the individual is abusing the drug. This quote is emphasizing the significance of understanding the distinction between leisure drug use and drug abuse. Recreational drug use is usually considered to be less harmful than drug abuse, as it is carried out in small amounts and is not done on a regular basis. Substance abuse, on the other hand, is more unsafe as it involves taking drugs in big quantities and regularly. This quote is a suggestion that leisure substance abuse and drug abuse are 2 really various things and should be treated as such.
