I really want to try this one, but with weed: Chemical doping - There has been some pioneering work in this area done by Adam Gottlieb.
Increasing the levels of the precursors that lead to mescaline has proven to be a relatively quick and effective way to significantly increase the level of mescaline in a Cactus. There are three major precursors to mescaline, namely dopa, tyramine and dopamine. During mescaline synthesis in the plant, tyrosine is broken down into tyramine and dopa. These then combine to form dopamine, which is later converted to nor-mescaline, and of course mescaline.
It is possible to take advantage of this synthesis route, and use it to vastly increase the mescaline content of the Cactus that will be harvested.
This method can be used successfully on any mescaline bearing Cacti. The steps are as follows:
1. Withhold water from the plant 2 weeks prior to doping. This helps the plant to absorb any injected material more readily.
2. Prepare a saturated solution of free-base dopamine in a .05 N solution of HCL. If dopamine is not available a second best alternative is to use a mixture of tyramine and dopa.
3. Inject approximately 5cc of the solution, half towards the bottom of the plant by the roots. Inject the other half into the green tissue at the base of the plant, and in several other spots up the stem. Do this slowly ,carefully, leaving the needle in place for a few seconds to allow absorption.
4. Wait 4 to 8 weeks before harvest to let the additives metabolize and convert to mescaline. I would not stress the plant during this period, as an actively growing plant is necessary for efficient metabolism.
5. The harvest can be delayed further and a series of booster injections can be given every 6 - 8 weeks to bolster alkaloid levels even more.
