Whats the difference between Cannabis and Hemp?

This is a bit of a misinformed question and has quite a lengthy response to untangle and debunk. There will no doubt be a blog post on it soon but in the meantime, in its simplest formation, we can provide the following to aid in an informed definition for the future:

Hemp is Cannabis! Although hemp will not get you ‘high’. Hemp is a term used to describe a strain of Cannabis Sativa L. which is grown for industrial purposes and has a THC content of less than 0.2% when grown within the UK/EU. Recreational or medicinal cannabis (Marijuana in the US) has a THC content of greater than 0.3% and the plants tend to be grown/engineered to maximise the growth of the flowering bud which contains the greatest concentrations of THC. Conversely, Industrial hemp grows to maximise the length of stems and other attributes which increases its own uses for industrial applications such as textiles, plastic alternatives and parchment.
