We set 10-mg limit in CO for recreational edibles, but left medical where it was, no particular regulations. I get an edible that's 225-mg but divided into 10 pieces. I eat b/w 44- and 88-mg when I medicate.
10-mg is very low, very safe.
Thing is, I know lots of people that smoke wildly various amounts regularly, as there seems to be little correlation b/w, smoking tolerance and edible "tolerance" (or tolerability might be a better term). Edible tolerance will settle in as you continue to dose edibles. You'll find your sweet spot.
I'd say start with 30-mg and then do the standard - wait two full hours and dose more if you need. When you get to where you want you'll know what you like. Though, if it takes you several re-doses to get the right effect, remember that next time you'll need somewhat less than the total you consumed during your trial b/c some metabolized during your trial run. So, if you had to titrate up to say 100-mg (that's a high end for almost eveyone I know taking professionally made edibles, until they get a big tolerance) maybe only dose 80-mg the next time. Should be about the same.
Always consume with some fatty food in your stomach, recently consumed, and you'll get the most out of it. Edibles on an empty stomach can have a much muted response, possibly leading to overestimating needed in the future.
Dosing too high will ruin your experience. Always can take more, not less. Give every increment two full hours to take effect.
Enjoy!
Edit: my edibles are 225-mg divided in ten pieces, not 10-mg increments. So I usually dose by the piece, starting at two pieces, so ~45-mg, then I'll take one piece every two hours until I'm good. Sometimes 45-mg is fine, others I'll go up to ~90-mg. Anything over 100-mg gets very weird for me. I believe the variability in response isn't so much poor dosing by the manufacturer, but rather my mood, pain level, smoking habits, stomach contents and the oddities of my benzo taper. If I didn't mention above it's Blue Kudo bars that I buy and eat, and only them. That's only useful info for my fellow residents. They do make recreational bars as well. Just capped at 100-mg per package, and divided into ten "doses" for consumer safety. And it costs more... So glad I'm legit medical when it comes to tax, pricing and choice.
Edit 2: the edit above makes it seem as if I vary my dose most times. I don't. Almost always three pieces does me fine. So, most often I dose at about 68-mg (3x22.5 +/- some). That's an amount I'll sometimes take all at once, if I'm going to be doing nothing much, as I easily can handle it if that is a bit more than I probably needed. If I need to go up to 90-mg I do so in several increments, errors at that dose can be uncomfortable for me. Rarely do I need more than 68-mg.
