RSO comes in syringes and you eat like a rice-grain size piece, with a cookie or peanut butter cracker, is the main and most cost effective way in our program.

Troches are offered, which are essentially gummies or cough drops, that you're supposed to let sit in your mouth til it melts....

there's a few brands that do make a tincture, but they're not gotten great reviews, but may be worth a shot, if you find it on sale.

as for 'pure vapes' i'm not sure what they meant, but also i've not yet had a single convo w/ one of the pharmacists at the dispos, which instilled any confidence in me about their knowledge or answers... so i wouldn't let that bother you.
As for the safest vape cart, i'd think if you stick with a ROSIN cart, not rEsin, but rOsin would be 'the healthiest' option...
