As a raver I think I may of had a mate who drove home while on something…
I think being stoned can make young men who drive like dicks much much safer.
Years ago a motorcycle magazine did a test on driver safety hazard perception and reaction times. Booze was bad as we know. I can’t remember what the drugs were or the result exactly, but the results were not a shock. Tiredness and severe cold had a huge negative effect and combining the two was shockingly bad.
If the OP is that bothered why not go and have a chat with the neighbour?
