Onset of effect refers to the time span between consumption and the moment an effect becomes noticeable. It heavily depends on the method – and precisely this difference is often underestimated. The onset of effect is one half of the picture, the duration of effect is the other.
What determines the onset
The route of administration is crucial. Active ingredients reach the bloodstream very quickly via the lungs, much slower via the gastrointestinal tract. Bioavailability and individual factors such as metabolism also play a role. Therefore, no exact, universally valid value can be given – only rough guidelines.
By method
When smoking and vaping, the effect usually sets in within a few minutes. With edibles, it often takes 30 to 120 minutes, because the path through digestion is longer. For tinctures taken sublingually, the onset is usually somewhere in between. The slow onset with edibles is why their effect is easily overestimated or more is taken too soon.
Frequently asked questions about the onset of effect
What works fastest?
Absorption via the lungs – i.e., smoking and vaping – usually within a few minutes.
Why do edibles take so long?
Because they first have to be digested and processed by the liver. This delays the onset to often 30 to 120 minutes.
Are there fixed times?
No. The onset varies individually. Only rough guidelines per method can be given.
