鈥淐annabis is a safe, versatile and potentially inexpensive drug,鈥� says GW
Pharma of Wiltshire. It can also reduce pressure inside the eyeball in glaucoma
patients, and its anti-vomiting properties are useful for patients on
chemotherapy. But cannabis smoke contains even more tars than tobacco, and
chemotherapy patients cannot keep oral capsules down long enough for them to
take effect. The patented answer is an under-the-tongue spray that delivers
controlled amounts of the active ingredient tetrahydrocannabinol along with
ethanol and flavouring oil as an aerosol in butane gas (GB 2361869). It is
quickly absorbed and there鈥檚 no need to swallow.
