just wait for e-pot smoking...
That’s been around since before e-cigarettes came out.
The vaporizer technology in e-cigarettes derived from devices designed for marijuana use. Big contraptions, those early vaporizers. They heat the weed until the active ingredients vaporize, before the weed itself actually combusts. Many of the devices sold in medical marijuans shops today are pre-loaded e-cigarettes (loaded with THC oil).
And yes, the nannies are already up in arms about it.
