Nasty sides (as they all seem to have). From Wiki:
[h=2]Adverse effects[/h]Data from clinical trials submitted to regulatory authorities showed that rimonabant caused depressive disorders or mood alterations in up to 10% of subjects and suicidal ideation in around 1%, and in Europe it was contraindicated for people with any psychiatric disorder, including depressed or suicidal individuals.[SUP]

Additionally, nausea and upper respiratory tract infections were very common (occurring in more than 10% of people) adverse effects; common adverse effects (occurring in between 1% and 10% of people) included
gastroenteritis, anxiety, irritability, insomnia and other sleep disorders, hot flushes, diarrhea, vomiting, dry or itchy skin, tendonitis, muscle cramps and spasms, fatigue, flu-like symptoms, and increased risk of falling.
The FDA's advisory committee raised concerns that based on animal data, it appeared that the
therapeutic window with regard to CNS toxicity, and specifically seizures was almost nonexistent; the therapeutic dose and the dose that caused seizures in animals appeared to be the same.[SUP]

When the EMA reviewed
postmarketing surveillance data, it found that the risk of psychiatric disorders in people taking rimonabant was doubled.[SUP]
