Question: how long does the effect of bhang take in passive smokers

Jacinta Nzilani answered on 17 Jul 2025:

Hey,
In passive smoking, the effect is usually very minimal or none at all unless:

1. You’re in a closed, unventilated space (e.g., a car or tiny room)

2. There’s heavy smoke for a prolonged time

3. The cannabis being smoked is very potent

In those rare situations, the effects might kick in within 15 to 30 minutes and last a few hours, depending on your sensitivity.

🧠 Possible Effects in Passive Smokers:
Mild dizziness

Slight headache or lightheadedness

Red eyes

Sleepiness or being “spacey”

But this isn’t common unless you were heavily exposed.

📚 Scientific Note:
Studies (e.g., Johns Hopkins, 2015) show that in extreme cases (like being in a sealed room), non-smokers can absorb THC, the active compound in bhang, and might even test positive in a drug test for a short while.

⏱️ How Long Can It Stay in the Body?
If exposed heavily, THC may be detectable for up to 24–48 hours.

Light exposure? Probably gone in a few hours and often not detectable.

🌬️ Final Thought:
If you’re just around bhang briefly or outdoors, the chances of feeling high or testing positive are extremely low. But still, it’s good to avoid those smoky spots, especially if you’re concerned about health, performance, or school rules. 😅
