Driving on the road after cannabis consumption – what actually applies? And how does that work with CBD hemp? Unlike alcohol, the rules that apply to cannabis on the road are not yet part of general knowledge in Switzerland. There are well-known principles (“No drugs at the wheel”). However, these are only moderately helpful when it comes to specific everyday situations. <\/p>\n\n
The legal THC limit in road traffic is 1.5 ng\/mL blood serum<\/strong>. That sounds clear, but it is not. It is an “analytical limit value”. Whether driving ability was actually impaired is irrelevant. <\/p>\n\n In the case of alcohol, 0.5\u2030 is the value at which driving ability is scientifically proven to decrease. This value is based on numerous studies. The THC limit, on the other hand, has been set so low that it is de facto equivalent to zero tolerance<\/strong>. <\/p>\n\n The zero tolerance is justified in different ways. On the one hand, cannabis is illegal anyway, so strict rules are needed. On the other hand, experts argue that it is difficult to set a fair limit, as the effects and degradation of THC vary greatly. <\/p>\n\n The problem is that consumers cannot know how much THC they have ingested. Different strains, frequency of consumption and individual metabolic rates influence the values. There is no practical relevance<\/strong> here as with alcohol (a glass of wine \u2260 0.5\u2030). <\/p>\n\n CBD hemp may contain up to 1 % THC<\/strong> in Switzerland. This is not normally sufficient for values above 1.5 ng\/mL, but can falsify rapid drug tests. <\/p>\n\n A positive test leads to complex proceedings: Blood and urine samples, provisional withdrawal of driving license and high procedural costs. Regular users can still be over the limit days later – even if the effects have long since worn off. <\/p>\n\nZero tolerance – background and criticism (H2)<\/h2>\n\n
