What is the safest drug to use after weed?

you just need to find a way to rekindle the love with thc. try differnts forms (hash,oil) or differnt smoking methods (bong, lung, gravity, vap,) there's no other drug that you can just use everyday with out having really negative effects other then weed. (actually i take that back try kratom not sure of any stores that cell it but you can buy it on ebay)
