You will find Peruvian Torch for sale online in the form of cuttings and potted live cacti. You can also buy dried Peruvian Torch from retailers such as Everyonedoesit, a vendor we have come to respect over the years and who always deliver an excellent service and quality product.
Peruvian Torch is legal in most parts of the world, the only country we have come across where it is not legal in any form is Switzerland. There are several other countries where the cactus itself is legal but if it is prepared for consumption or dried then it becomes illegal. Please, always check local laws!
