Bright light (as one natural reason). Opiate based drugs and medications can cause pinpoint pupils.
The drugs that most commonly cause constricted pupils or "Pinpoint" are strong opiods such as Heroin, morphine, oxycodone, or high doses of norco / vicodin.
morphine and methadone.
they all cause cancer but not the good drugs like Advil
for the illegal drugs: the withdrawal of opioids such as morphine is known to cause mydriasis.
Prescription drugs that can cause the pupils to contract are drugs from the opioid family. Morphine and codeine-dionine drugs are in this group. Others are hydroxy-morphine, dinitrophenylmorphine, and benzylmorphine. These drugs are used as pain killers.

Yes, it can, I have been on methadone for two + years and have been clean and sober off all other substances during the entire time I have been on methadone. I was recently accused of using substances again due to pinpointed pupils and severe sweats,,,,both these are caused and are side effects of methadone maintenance. I have two + years of clean urinalysis to back these claims up so this is a fact. METHADONE PINPOINTS PUPILS.....
yes because illegal drugs can cause heart defects contributing to a heart murmur.
Your pupils enlarge in dark light so more light comes in. They constrict in bright light to reduce the amount of light. They are affected by drugs. Many abused/illegal drugs causes the pupils to constrict. This is a neat exercise. Rub the short hairs on the back of your neck below your hairline. Your pupils will constrict and enlarge. It is not known why this occurs. There is a theory that when people lie, their pupils dilate.
