Yes Kratom is legal in India. Though, not available OTC but you may order it online and the delivery is safe.
The effects are nowhere near an opiate but however it does help get off opiates and can prove to be a temporary remedy for the addicts with limited or no supply of their regular opiate. The kratom benefits is not checked at the customs too as the order package is named as “incense” and moreover as it is a useful product to get off opium the government is not so against the use.
The addiction is very rare.
