"not sure" is where you have to be REALLY CAREFUL when playing with lasers. Weed is temp sensitive for what oils you drive off and what you burn. A laser gives you the chance to decompose those things further or preferentially make one product you really don't want. Like cyanide.

true i think if i did weed i'd just stick to edibles only way you make toxic smoke with those is if you are very bad at baking
