That ain’t the problem w bm carts. At least in the US synths ain’t a problem and are very rare for the most part. Shit even cut oil is on the decline at least in my area it’s hard to get a weak cart round here. Regardless the problems w bm carts are cleanliness and cuts. Cleanliness meaning the very vast majority of bm carts either have contaminated oil (pestis chem residue heavy metals fungus etc.) and/or come into contact w shit hardware made by sum sad 9 year old in China w lead components that I can guarantee will fuck u up eventually. Ion like speaking in absolutes but that’s a promise I’m willing to make. Mandatory lab tests in legal states are there cuz it’s very hard to get clean safe product, the plant is prone to absorbing heavy metals very well so a lot is thrown out when tested cuz it simply ain’t meet safety standards. Cuts ion think I need to cover. We all saw the evali cases and how dangerous cuts can be. PG/VG is carcinogenic, vit e is straight up dangerous, and there’s def other cuts I ain’t know of that could be in use. I smoke bm sometimes. I ain’t above it. But I always go into whatever I cop knowing the potential risks and being prepared to accept any consequences there may be. I’ve prolly shaved a few years off my lifespan and u def ain’t doing any better than me. Put down the carts, cop an 1/8 of gas weed, and enjoy the j or blunt u deserve. Is it clean weed? Prolly not. But it’s far safer than street carts will prolly ever be
