I was told that “one good joint” would have the same hypervigilant effect that a lifetime practising martial arts would have. So, on a gap year to Canada, I tried it. With an English accent, I was invited to lots of parties with abundant cannabis. I returned to the UK with my personality in tatters. After three years, and seven suicide attempts, I wound up on an open ward. While the prescriptions increased, my cannabis habit remained. Then, I realised that I had the power to stop. I’ve since written and lectured extensively about this journey. I curate two podcasts.
