Heroin use can cause constriction of the eye's pupils, resulting in smaller or pinpoint pupils. This effect is known as miosis. The pupils may react less to changes in light when someone is under the influence of heroin, leading to slower responses to light stimuli.
Pinpoint pupils caused by heroin use typically last for 4-6 hours after administration. It is important to seek medical help if pinpoint pupils persist or are accompanied by other concerning symptoms.
Not in most fish, but flat fish and eel pupils change in size according to the amount of light they receive - like humans, these fish's pupils become smaller when there is plenty of light.
It depends quite heavily on ones tolerance to the drug. Pupils will generally stay constricted for the duration of the euphoric experience. Depending on quantity and quality of the heroin, and as I said the higher a person's tolerance, the faster they come down which is when pupils will return to normal size.
They will return to normal size not long after the high is over. How long the high lasts depends on how it's administered.
pupils of the same size
No; the change in the size of your pupil is an involuntary action, meaning that it happens without you thinking about it. The size of your pupils adjust to stimuli, such as bright light. If a bright light was shined in your eyes, your pupils would get smaller in order to let as little light in as possible. Reversely, if you're in a dark room, your pupils will get bigger to let in as much light as possible.
Dilated pupils not responding to light occurs in deep coma and death. The iris doesn't contract, thus pupils fail to automatically respond to light.
Abviously not. Hence tha pupils changing size.
