LSD can  be  administered  a number  of  ways,  the  most
            common:  orally through  paper, sugar cubes,  on a piece  of
            gelatin, or by pill;  intravenously; or intramuscularly.  A
            standard dose  with  noticeable  hallucinogenic  effects  is
            about 100-200 ug.  The intensity of the trip is proportional
            to the  size of  the  dose --  it  is interesting  to  note,
            though, that the duration of the trip seems to stay the same
            at higher doses (Freedman, 1984).  The initial effects begin
            20-40 minutes  with  a  sense  of  euphoria  and  dizziness.
            Hallucinations then begin  to occur, with  the trip  peaking
            for 4-5 hours after about an  hour since the drug is  taken.
            LSD is best described as a drug that strikes down  barriers.
            The person  who uses  LSD is  likely to  feel detached  from
            his/her ego, and can cross between states of  consciousness.
            The user's  perceptions  are  altered,  causing  visual  and
            auditory hallucinations.  One may  notice that the walls  of
            room are "breathing" or  that motionless curtains appear  to
            be moving.  Senses appear to  mix:  a user might see  music,
            taste colors, or hear visual stimuli.  The LSD experience is
            often difficult to describe by  users -- words lose  meaning
            and are often insufficient in describing the effects of  the
            drug; thoughts may  seem unclear.  Effects taper off  after
            about 6-8  hours and  are usually  completely gone  after  a
            nights sleep.
