Can i pratice wicca and smoke weed ?

I cannot advocate doing anything illegal, liking smoking weed, but I can tell you that if you live somewhere that marijuana is legal, there is nothing in the Wiccan religion against it.

However, if you are trying to use the relgion to justify it, try again.

Wiccans believe that things provided by the earth can help us in our daily journey, but we do not use “medicinal herbs” the way some other religions might. When it is not contrary to the law, Wiccans use whatever herbal remedies and gifts of he earth to their advantage. But Wiccans do not break the law in the name of religious practice.

There is nothing in the practice of Wicca to require or even suggest that smoking marijuana is going to make your worship more effective or your spells any more powerful. Using it for personal reasons is not forbidden, but it is not endorsed either.

In short, the decision to smoke or not is up to you. It has nothing to do with the exercising of the faith and the practice of witchcraft.

It is also a bad idea to be high while casting spells or performing rites. Rituals and spells require a clear mind and strong concentration. While smoking during things rites is not expressly forbidden, it will likely distract you and keep you from performing up to your potential.
