1. Gateway drugs can be used to self medicate for things like depression, which are prevalent in the community during pandemics. The number of people reliant on these drugs will increase.
2 I would give the advice of seeking therapy to get to the root issue of why you started drinking/smoking in the first place.
3 I would say I cannot risk my health.
4 As a student, I would say they are gross and do more harm then good. I dont want to risk my health for more potentially worse health issues.
^ these are all my best guesses hope that helps :) !!
