Which drugs slow down the pupil reflex?

When smoking weed, cannabis is inhaled, i.e. forms of cannabis such as grass, weed or marijuana are burned, so that the vapors can then be inhaled. This initially leads to a relaxing effect as well as euphoria and possibly hallucinogenic effects. This is followed by an increased appetite with ravenous appetite attacks.

The cannabis also leads to a dilation of the pupils. This can already occur with a normal amount of use, but is particularly the case with cannabinoid poisoning. When smoking weed, therefore, the pupils usually dilate (mydriasis), and the eyes often appear empty as long as the active substance is present in the body in sufficient dosage.

By intervening in the control of the pupil width, the pupil reflex can also be influenced. Often the reflex is slowed down, sometimes it is even barely present. As a result, even when light shines into the eye, the dilated pupil does not or only slightly get smaller.
