We live in different bubbles. I certainly live in a social circle that has a mature view on cannabis. Perhaps it's Amsterdam.
I smoke about 6 to 12 times per year, mostly THC/CBD (Dutch weed), sometimes CBD only (specifically, weed from Switzerland).
Dutch weed: 3 to 5 puffs and I'm fine. Smoking half a joint or more is definitely overdosing it, feeling cold and uncontrollable tremors can occur.
Swiss weed: I smoke half a joint.
