Drug paraphernalia Drug paraphernalia "Drug paraphernalia" is a term, to denote any equipment, product or accessory that is modified for making, using, or concealing drugs, typically for recreational purposes. Drugs such as cocaine, heroin, marijuana, and methamphetamine are related to a wide range of paraphernalia. Paraphernalia generally falls into two categories: user-specific products and dealer-specific products. User-specific products include glass hashish pipes, crack cocaine pipes, smoking masks, hashish bongs, cocaine freebase kits, syringes, roach clips for holding the burning end of a marijuana joint. Some stores sell items for growing hydroponic marijuana, such as guidebooks, fertilizer, and fluorescent grow-lights. The term "paraphernalia"
Nanoparticles for drug delivery to the brain to target specific organs and tissues in the body, to carry DNA for gene therapy, and to deliver larger molecules such as proteins, peptides, and even genes. To manufacture these polymeric nanoparticles, the drug molecules are first dissolved and then encapsulated or attached to a polymer nanoparticle matrix. Three different structures can then be obtained from this process; nanoparticles, nanocapsules (in which the drug is encapsulated and surrounded by the polymer matrix), and nanospheres (in which the drug is dispersed throughout the polymeric matrix in a spherical form). One of the most important traits for nanoparticle delivery systems is that
