Continuing to play devil's advocate, so please attack my arguments at your leisure...
Some context might be the amount of money that gets spent on a cocaine versus a flying habit.
A bit of searching around the internet suggests that a gramme of cocaine costs about £50, and a typical dose is about 1/10th of a gramme. So, about a fiver a dose. Toxic levels apparently start about a gramme a day.
Let's say that a reasonably heavy users takes cocaine twice a day. So that's 365 x £5 x 2 = £3,650 per year spent in cocaine. [Disclaimer, I have no idea if this is high or low, my total personal knowledge of drug use was a few people who smoked cannabis when I was a student.]
Comparing that to our 40 hr per year PPL, York flying school at Breighton show C150 hire at £100/Hobbs hour, so that'll be around £110 per logged flying hour. So, the sum is straightforward - a reasonably keen PPL will be paying about £4,400 per year to feed their habit.
So, my...
simple minded, context free, statistical analysis
(Yes absolutely) shows that as well as being half as likely to kill you, being a coke-head saves you about £1k per year compared to being a PPL.

Not going to save money by giving up his flying habit to become a coke-head, but finds the numbers interesting.
