"I started on the downers which were a hell of a lot better than the uppers because I was a nervous wreck"

This quote by Corey Haim is likely referring to his experience with drugs. The "downers" he is referring to are likely depressants, such as benzodiazepines, which can have a calming result on the user. The "uppers" he is referring to are most likely stimulants, such as drug or amphetamines, which can have an energizing impact on the user. Haim's declaration indicates that he was in a state of severe stress and anxiety and discovered the depressants to be more handy in soothing him down than the stimulants remained in stimulating him. This quote is a reminder of the risks of substance abuse and the significance of seeking expert help when dealing with mental health problems.
