Function

• Pollen presses are manual instruments that are used to compress pollen. They are suitable for small-scale use, producing just a few grams of compressed pollen with each use.
  
  

Features

• Pollen presses are simple pieces of equipment. They are usually cheap to buy or make. There are five pieces to a pollen press: the main body; two pins that fit inside the main body; and two caps that are screwed on at either end.
  
  

How to Use

• Pollen is collected and placed inside the main body of the pollen press. The pins are screwed tightly into place using the caps, forcing them inward and compressing the pollen. The pollen press is left shut for at least eight hours so that the pollen is molded into a fairly solid lump that can then be taken out of the pollen press.
  
  

Hashish

• Pollen presses are used in the manufacture of hashish, a derivative of the marijuana plant. Hashish is made from marijuana pollen that is compressed in a pollen press.
  
  

Illegal Use

• Hashish is an illegal drug in the United States.
