Yes. Used to be, if you wanted to become a supplier, the "applicant" who gained the trust of the families would be told to do a thumbprint of the raw crystal and lick it (just touching the crystal would be a massive enough dose via skin absorbtion). Those thumbprints can be the equivalent of 10,000x a normal dose. That's like eating 100 sheets. One man- forget the name- accidentally ingested 250,000x and set the record for highest known dose. All these people survived, but extreme doses like that leave you permanently changed. Most I've done in a sitting was a couple tenstrips, and while it was a good time, I'd never want to do that again (much less a fucking thumbprint). Point being: it's almost totally non-toxic in relation of active dose to mass.
