You're probably right that it's the case in most countries, but an interesting counterexample is Sweden, where testing positive on a drug test is a criminal offence. Police can arrest you for appearing to be under the influence of drugs, and if they find any traces in a urine test, they'll fine you for it.
I hope that legalization in Germany will lead to more sane laws in Sweden, but honestly, I'm not holding my breath for it
