In the UK last few years dry herb vaporizers becoming very popular. More and more people switch smoking to vaping, claiming lots of health benefits, clearer high, a way more pure taste of cannabis. Besides it takes much less amount of cannabis to vape in order to achieve the same result compared to traditional smoking. In the UK Medical Cannabis is legal since 2018 but pharmacies mostly sale IRRADIATED cannabis. Irradiated medical cannabis refers to cannabis that has been treated with ionising radiation to reduce the presence of harmful microbes such as bacteria, viruses, and fungi. This process involves exposing the cannabis to a controlled dose of gamma rays or electron beams, which can kill or inactivate the microorganisms. A recent study has shown that the most important therapeutically active components THC and CBD are not affected by the radiation. Herbal cannabis products, often used by vulnerable patients, are treated by gamma-irradiation to free them from contamination with potentially harmful microbes.
