Hash oil (Rick Simpson Oil) when taken orally over several months, may harden into a brittle plastic on your teeth. like Crazy glue. It combines with hard water minerals to form a dental calculus (tartar) which is hard as concrete, and may seal and deform your denture, leading to serious dental infection akin to Ludwig's angina, including rhabdomyolysis and systemic mycosis.

This plastic-mineral tartar (like asphalt concrete) is extremely difficult to remove from the teeth, and you will essentially need to cut the teeth apart.one by one. It makes you think of Jaws, the villain from James Bond movies.

There are no reports about this in the relevant cannabis literature. I guess this can also happen with other resins and lacquers, whether natural or synthetic ones, like with Crazy glue. Dental literature is also silent about this. --83.137.6.241 (talk) 18:58, 26 August 2021 (UTC)[reply]

Particularly watch out for dental composite tooth fillings, which are made of plastic and may become affected by hash oil. Probably the solvent used to extract the marijuana (in my case white spirit) together with the natural plasticizers in hemp resin may have softened my many plastic tooth fillings, so that they became deformed and stuck together. Two years later, I am still cutting my teeth apart. Smoke hash oil, but don't eat it :-) It is very sour (has a high acid value) and may cause ulcers in your stomach and intestine. --213.33.70.33 (talk) 00:54, 10 January 2024 (UTC)[reply]
