Many patients talk about how they are addicted not only to the drugs, but also to the ritual of drawing their drug up into the needle, and the act of injecting it. However, not all addicts who inject develop this sort of intense relationship with the act of injecting.
There’s sometimes a sexual aspect of injecting, or injecting your partner. One may notice the symbolism of the needle, the phallus that penetrates the body, and the sadomasochistic side of the pain of the needle and the pleasure that follows with the drug intoxication. Part of me wonders about this last part.
