Bhang contains THC — the same psychoactive compound found in cannabis. When consumed, THC crosses the blood-brain barrier and binds to cannabinoid receptors, altering mood, memory, and perception, and in some cases triggering psychiatric symptoms. Understanding these effects helps people make informed choices about their mental health. If bhang use is affecting you or someone you know, you can speak with a Cadabam's clinician.
What Is Bhang and Why Does It Affect the Brain?
Bhang is a preparation of cannabis leaves and flowers, ground into a paste and traditionally mixed into drinks such as lassi or thandai. Like other cannabis products, it contains THC (the psychoactive compound) and CBD.
Because bhang is consumed as an edible, its onset is delayed — usually 30 minutes to 2 hours — but its effects are stronger and longer-lasting than smoked cannabis, often persisting for 6–8 hours. This delay is significant: people who do not feel an effect quickly may consume more, leading to accidental over-consumption and more intense psychological effects.
Short-Term Effects of Bhang on the Brain
The immediate neurological effects of bhang appear once THC reaches the brain and bind to cannabinoid receptors.
Common short-term effects include euphoria, altered time perception, slowed reaction time, impaired short-term memory, dry mouth, and an increased heart rate. At higher doses, the experience can shift sharply — anxiety, panic, and paranoia are well-documented reactions. Because bhang is an edible, onset takes 30 minutes to 2 hours and effects can last 6–8 hours, meaning a difficult experience can continue for a long time once it begins.
Long-Term Effects of Bhang on Brain and Mental Health
Regular, heavy bhang use carries more serious risks for the brain and mental health, particularly when use begins early in life.
Long-term use is associated with persistent cognitive deficits affecting memory, attention, and decision-making, and with an increased risk of anxiety and depression. In people who are vulnerable, it can raise the risk of psychosis. The adolescent brain continues developing until around age 25, and persistent cannabis use during these years is especially harmful — a widely cited PNAS study linked persistent adolescent cannabis use with an average decline of around 8 IQ points. These findings underline why early and adolescent use deserves particular caution.
Bhang and Psychiatric Conditions: Who Is at Risk?
Some groups face a substantially higher risk of harm from bhang and should be especially cautious.
Adolescents, whose brains are still developing, are most vulnerable. So are people with a personal or family history of anxiety, depression, bipolar disorder, or schizophrenia — in predisposed individuals, bhang can trigger a psychotic episode. Pregnant women should avoid bhang entirely, as THC crosses the placenta and can affect the developing baby. People with heart conditions are also at risk because THC increases heart rate.
Bhang Withdrawal: What Happens When You Stop
People who use bhang regularly can experience cannabis withdrawal syndrome when they stop. Symptoms include irritability, sleep disturbance, reduced appetite, and restlessness. Withdrawal is not medically dangerous, but it is uncomfortable enough to drive relapse. Symptoms typically begin within 1–2 days of stopping and last 1–2 weeks. Cravings during this period are real, and support makes them easier to manage.
When Bhang Use Becomes a Mental Health Concern
There is a meaningful difference between occasional, festive use and a pattern that has become problematic. Warning signs include using more than intended, experiencing cravings, neglecting responsibilities, using bhang to manage difficult emotions, and noticing mood changes when not using. If casual cultural use has shifted into a regular pattern that affects daily life, a professional evaluation is worthwhile — and seeking help is a practical, non-judgmental step.
