Buy a San Pedro Cactus

The San Pedro Cactus is originally from South American countries such as Chile, Bolivia, Ecuador, and Peru. It grows in the high Andes mountains and was used for shamanic and religious purposes. The mescaline in the cactus can lead to intense journey experiences such as hallucinations and altered perceptions of reality. The effects are similar to those of LSD, mushrooms, and magic truffles but definitely have their unique character.

You can grow a mescaline cactus like San Pedro, Peyote, or Peruvian Torch yourself, but this is challenging and usually takes a long time. Germinating cactus seeds is complicated, and growth is very slow. San Pedro cactus is one of the fastest-growing species and can grow from 10 to 50 centimeters per year. So, it takes a long time to accumulate enough mescaline for a trip. That's why it's better to buy these San Pedro cactus cuttings.

Mescaline Cacti

These cacti naturally contain the psychoactive substance mescaline. However, this substance is in a slightly different form than pure mescaline. That's why you need a significant amount of a cactus like Peyote, San Pedro, or Peruvian Torch to achieve the same effect as chemically prepared pure mescaline. On the other hand, you can experience something unique using a natural source. The effects are comparable to a trip with mushrooms, ayahuasca, or LSD but often last longer, and the nuances are certainly unique. The effects start 45 to 90 minutes after ingestion, often accompanied by tasting the acidic flavor of the cactus again, leading to potential vomiting. According to the shaman and the medicine man, this is part of the experience. The peak occurs between four and six hours after consuming the cactus, and the total trip lasts from 6 to 14 hours.

Preparing the San Pedro Cactus

You can consume the cuttings of this San Pedro mescaline cactus. Sometimes, spines grow on the San Pedro. You should then remove the spines and peel the cactus all around. Afterward, the San Pedro is ready for use, and you can experience an intense trip. However, the mescaline cactus is generally not consumed raw. It is often transformed into mescaline powder or tea from these San Pedro cuttings. You can find instructions for preparing the San Pedro cactus in our blogs.

Mescaline Dosage

The amount of mescaline in a San Pedro cactus can vary greatly. You can assume that a 100-gram piece of fresh San Pedro cactus contains an average of 50 to 120 mg of mescaline. It is important to take an appropriate dosage. Below, you will find the right mescaline dosage.

  • 150 mg - light trip - barely noticeable effect
  • 150 to 300 mg - light to moderate trip
  • 300 - 400 mg - strong trip - can last from 6 to 14 hours
  • 450 - 500 mg - very strong trip - can last from 6 to 14 hours
  • 500 - 600 mg - very heavy trip (for experienced users only) - can last up to 24 hours

For more information on dosage and preparation, consult our blog.

Storing, Drying, and/or Replanting the Cactus

San Pedro's, Peruvian Torches, and some other mescaline-containing cacti are fast-growing cacti. As mentioned earlier, 150-200 grams of fresh San Pedro is often enough for a strong mescaline trip, and there is often a piece (cutting or torch) left. You must take good care of the cut if you want to reuse the cactus later. Only cut with a clean, very sharp knife. It's best to briefly hold the knife in the flame. Above a gas stove or with a blue flame lighter, your knife is thus disinfected. Let the knife cool before cutting. This way, you avoid infections on the piece you have left.

Storage Outside the Refrigerator

You can store such a cut piece for up to 3 months after cutting. Wrap the spiny stem in several layers of kitchen paper and store it in a kitchen cabinet out of reach of children and pets. We do not recommend storing it in the refrigerator because the relative humidity is often too high.


By storing the cactus as described above, it already loses moisture. The cactus is then immediately ready for use or can be replanted. However, if you want to dry it completely, be aware that you will not be able to replant it later. Drying has the advantage of increasing the mescaline concentration per gram of cactus, meaning you need to take less for the same effect. Cut very small pieces. The smaller, the better they can dry. Spread the pieces on kitchen paper in a large baking dish or on a plate. Place a glass in the middle and cover it with a clean, dry kitchen towel. Place the dish or plate in a location out of reach of children or pets. Change the kitchen paper daily. Within 5-7 days, your cactus pieces will be dried. You can then store them in a ziplock bag, preferably with a sachet of silica gel (don't worry, they are not toxic as long as you don't eat the sachet itself).

Reproduction of San Pedro and other mescaline cacti (replanting)

If you want to replant/repropagate San Pedro, Peruvian Torch, or other mescaline cacti*, follow these steps.

*These instructions do not apply to Peyote cacti. For those, it's best to use a whole cactus (button) at once.

  1. Recently cut a cactus? Gently blot some kitchen paper on the wounds of the mother plant and the cutting to absorb most of the wound fluid. Then, place the cutting in a warm and dry place with indirect light, where it is a maximum of 25°C. Note: not in direct sunlight!
  2. Before you can replant the cactus, the wound must first dry well. The duration depends on the size of the wound. Long cuttings with a small wound are ideal. Let the cutting rest for at least a week, then check if it is completely dry.
  3. Do you see dots or spots on the cactus's wound? The wound may be infected. Cut off a piece of 0.5 centimeters and try to let the wound dry better.
  4. Fill a pot with holes in the bottom with a mixture of sand and potting soil. This combination is necessary for drainage. Place the dried cutting in the middle of the pot, about 3 centimeters deep. Put the cactus cutting back in a warm place, away from direct sunlight, just like the mother plant.
  5. Wait until the plant has rooted (this takes about 3 to 6 weeks), then give it small amounts of water. If the cuttings have been successful, you can give it more water and light over time.

First of all, I like that this is actually enough to make a strong concoction. I've shared this cutting with a friend.
Tip: Take off the waxy outer layer. The dark green skin underneath actually contains most of the mescalin. You don't want to water it down by adding the spongy stuff in the center. Peel it like a tough cucumber and use the leathery skin to make your mescalin infused drink. Toss out the white stuff.
