Guns may be more effective but I'd argue OTC meds are "easier" considering you don't get NICs checked for tylenol. And frankly many suicidal people (not all ofc) already have a problem with a particular drug that causes 96,000+ accidental deaths/yr, shooting of another nature, which kills 36,000 more people than guns/yr including suicide, that could also be used quite easily and peacefully as opposed to doing your best impression of Dead from Meyhem.

Simply banning guns wouldn't help, we still need to address the root causes. And once we address the root causes gun control will be a whole lot less necessary anyway. At the very least, we should start with the things that will be actually helpful and then move to the pointless bans which worked so well for those drugs 96,000 people OD on each year.
