The syringe contains the drug methamphetamine (meth). It puts meth
norns in a state of euphoria in the short term. (They get very happy,
indeed). In the long term, symptoms appear that are similar to those
found in human meth addiction - e.g depression, aggression and loss of
appetite. Requires meth norns that have their genomes specially
altered so that they produce neurotransmitters such as dopamine and
serotonin. If you know someone who is prone to experimenting with drugs,
why not show him or her the the consequences on norns instead.
