How To Recrystallize Methamphetamine

How to Recrystallize Methamphetamine


Methamphetamine is a powerful and highly addictive stimulant drug. Recrystallization is a process used to purify the substance by removing impurities and obtaining methamphetamine in its pure form. To ensure the safest and most effective results, it is essential to approach this process with caution and prioritize personal safety. This article explains the essential steps involved in recrystallizing methamphetamine.

Materials Required

Before diving into the process, gather the necessary materials:

  1. Lab coat, gloves, and safety goggles for personal protection
  2. Heat-resistant glass container or beaker
  3. A stirring rod or glass stirring rod
  4. Clean, lint-free filter paper
  5. Filtration apparatus (such as a Buchner funnel and vacuum pump)
  6. Ice or a cold water bath
  7. Clean methanol (preferably anhydrous)
  8. Non-polar solvent (such as acetone or toluene)
  9. High-purity methamphetamine

The Recrystallization Process

Step 1: Prepare and Set Up

Ensure you are working in a well-ventilated area, preferably a laboratory or a space equipped with appropriate safety measures. Wear a lab coat, safety goggles, and gloves to protect yourself. Set up the filtration apparatus, securing the filter paper in place.

Step 2: Dissolving Methamphetamine

Measure out the desired amount of methamphetamine and add it to the heat-resistant glass container. Select a container that can withstand the heat during the recrystallization process. Add a minimal amount of clean methanol to the container and create a solution by gently stirring with a stirring rod. Ensure the methamphetamine is fully dissolved in the solvent.

Step 3: Precipitation

Once the methamphetamine is fully dissolved, place the glass container in a cold water bath or add ice to cool the solution. Gradually and dropwise, add the non-polar solvent (such as acetone or toluene) to the cooled solution while stirring constantly. The methamphetamine molecules will gradually come out of the solution and precipitate as crystals. The impurities will remain dissolved or separate from the pure methamphetamine.

Step 4: Filtration

As the methamphetamine crystals form, carefully pour the solution into the filtration apparatus. The filter paper will capture the impurities, allowing only the purified crystals to pass through. Apply a vacuum using the filtration apparatus to speed up the process and promote efficient filtering.

Step 5: Drying

After filtration, allow the crystals to fully dry. This can be achieved by placing them on a clean, lint-free surface at room temperature. Alternatively, a gentle stream of air or a desiccator can be used to speed up the drying process. Ensure the crystals are completely dry before proceeding to the next step.

Step 6: Storage

Transfer the dried methamphetamine crystals into a clean, airtight container for storage. Store the container in a cool, dry place away from direct light.


Recrystallizing methamphetamine is a delicate process that requires careful attention to detail and adherence to safety protocols. It is crucial to prioritize personal protection and carry out the process in a well-ventilated area. Following the outlined steps, including dissolving, precipitation, filtration, drying, and proper storage, will enable you to obtain pure methamphetamine crystals while eliminating impurities.
