I've always viewed LSD as one of the safest drugs out there because of it's low short and long term harm to the body and mind and it's very low potential for misuse. The only real harm that I see associated with the use of LSD is the potential harm the user has to himself or others while under the influence. Having taken LSD myself several times, I have a hard time picturing myself actually doing any harm while on it as a great part of me still feels sober, like my judgement (I don't think I would do anything on LSD that I wouldn't do when sober). The thing is that I've now actually heard of two different accounts from two different friends where someone has become completely mental on LSD, even to the point of becoming violent towards his/her own friends. These instances are so severe that it makes me think that this stuff is actually really dangerous, but everything I've read tells me that the probability for this happening is really really small. What is your take on this? Could they have been taking something else than LSD? Or aren't these violent episodes as rare as I've been made to believe?
