challenge perceptions

Cannabis Skunk Sense (also known as CanSS Ltd) provides straight-forward facts and research-based advice on cannabis. We aim to raise awareness of the continued and growing dangers to children, teenagers and their families of cannabis use.

We provide educational materials and information for community groups, schools, colleges and universities; and guidance to wide range of professions, Parliament and the general public - with a strong message of prevention not harm reduction.

Here are some ideas from CanSS for excuses for not accepting or buying drugs:
