You will still need to wait another 6 weeks or so.
This plant has only started flowering and would only contain a very, very, very, very small amount of THC and not enough to have any effect.
These flowers will grow much, much bigger.....as it gets closer to being ripe, the pistils/hairs will start turning brown.
Once there are 98-99% brown pistils/hairs, you will be at harvest maturity.
