The word 'hemp' for many people still conjures up images primarily related to its use as a mood altering drug. While Cannabis Sativa is certainly abused extensively for illicit and 'recreational' purposes, it has many other applications. In fact, industrial hemp contains very little of the psychoactive substance found in marijuana and is an extraordinarily useful plant that can provide more environmentally friendly food, fibre, fuel, medicinal and building products.
Hemp, aka weed, is called that for good reason - in some places it is invasive and is considered a noxious weed. Some varieties are very hardy and able to thrive in harsh conditions. It's these characteristics that make it a great candidate to replace pesticide and herbicide dependent crops such as cotton. Hemp is also a water miser and can be processed into useful products with little energy and without requiring toxic chemicals.

And here's a very important fact. As useful as hemp is; the abuse of marijuana as a drug and consequent effects should not be underestimated.

Marijuana, Cannabis, Hemp, whatever you wish to call it is not a 'soft' drug. It can create emotional dependency, remove motivation, slow down response times and in some cases induce terrible psychotic bouts if the person using it is predisposed to mental illness. Never let anyone tell you any different. If used for medicinal purposes, then it should be prescribed and monitored by a suitably qualified medical professional.
The abuse of hemp aside, it's truly an amazing plant that Western society should be making far more use of in an effort to reduce our impact on the environment.
