As simply stated as possible:
Lysergic acid diethylamide (LSD) bonds to seven-transmembrane domain receptors associated with nerotranmitters. It bonds easily with all dopamine receptors and subtypes, all adrenoreceptor subtypes, and most serotonin receptors. Activating these receptors in neurotransmitters results in euphoria, the physiological manifestations of LSD use, and can (often does) result in aural, visual, and somatic (kinetic) hallucinations.
Physically, no, LSD is not bad for you. However, you can have a bad trip regardless of if you know how to use it or not and these trips may cause anxiety, depression, and flashbacks.
The most common problem with LSD is the "bad trip" experience where they experience extreme fear, paranoia, depression or panic. If LSD is used regularly it often causes mental illnesses. Some people complain that they suffer flashbacks long after a trip.

Yes, it is physically possible to mix LSD with weed and smoke it in a bong. However, the effects of smoking LSD are not well understood, and combining it with weed could potentiate the effects and increase the risks of a bad trip or negative side effects.

The chemical in LSD responsible for the psychedelic effects is LSD itself, lysergic acid diethylamide.
