Opiates should be legal, because banning them fuels the Taliban / Mexican cartels and does great harm to innocent people smart enough not to use it. Opiates are also next to worthless when it comes time to deal with real pain like bone metastasis - don't believe the liars when they say they can help your relatives; they'll get to the maximum and shrug when it happens.

Kratom may be not as bad as opiates according to some sources, but should be avoided by anybody not already addicted to opiates (or Kratom). People are slaves too many ways already without being physically slaved to some shitty class of drug that gives them painful constipation all the time. (Opiates do work for that!) The law can't and shouldn't help you - your brain can and should!
