The price-per-kilo of ketamine in online UK-based markets dropped 75% in just over 2 years. Why is it so cheap?

I spoke to DM Trott (author of The Drug Users Bible) about his five favourite drugs – of 182 he's tried, tested and reported on.

Can you guess the ketamine-adjacent research chemical he picked at number 3?

Happy to be told otherwise and god bless British pubs and clubs, but these longer hours aren't going to stop the 75% of booze being bought in shops, are they?

"The reason pink cocaine is “one of the most significant developments in the drug market in recent years” (according to a recent Spanish government report) is...because it’s pink. A bright, lurid, Barbie Dreamhouse pink that really pops on Instagram. "

I wrote a piece about the rise of “pink cocaine”, a drug for the modern age, in Colombia, Spain and now in the UK.

"Within half an hour I felt a cranial throb – like the ghost of a pill, dialled way down."

"Writing out lots of different substances may not appear concise on the death certificate...it's not always clear which drug was most responsible, so the cause of death is often reported as something ambiguous like “multi-drug toxicity” or “polydrug use.”"

At core, ADHD is a dopamine deficit. Which makes evolutionary sense of why those with it can gravitate to drugs, dancing, loud music, and the dopaminergic hunt of the sesh.

It’s a symbiosis with lows but abundant highs, shaping not just people but culture👇

Chronotherapy – aka “wake therapy”. Used with 1000s of patients for depression and bipolar.

But what is it, and why is there a lack of research on this extremely tiring treatment?
