What are
hallucinogens?
Hallucinogens are
drugs that cause hallucinations. Sometimes referred to as psychedelic drugs,
hallucinogens cause severe distortions in the user’s perception of reality.
Users experience a ‘dream-like state’ often seeing, hearing, tasting and
smelling things that are not there. Examples of hallucinogenic drugs include: Ecstasy,
LSD, and Ketamine just to mention a few.
What is HPPD?
HPPD is a condition
that results from taking hallucinogenic drugs, usually on a number of
occasions. People who use hallucinogenic
drugs like those mentioned above sometimes get flashbacks of the effect of the
drug days, weeks or even years after they’ve used it. For some, the experience of reliving the
effects of the drug taken is pleasant, sometimes even pleasurable. For others
however, they experience disturbing visual effects such as distorted sizes or
colours and bright lights that won’t fade. HPPD presents itself in two types:
- Type 1: people experience HPPD in the form of random, brief flashbacks.
- Type 2: people experience ongoing changes to their vision, which may come and go.
Although it’s still a poorly understood medical
condition, it’s not life-threatening. However, effects of this condition on the
daily life of users can be very distressing, so much so, that sufferers can end
up with mental health issues. A study
conducted by Dr. Henry Abraham, a
lecturer in psychiatry at Tufts University School of Medicine found that up to 65% of those with HPPD suffer from panic attacks due to their visual changes while up to 50% will be diagnosed with major depression as a result of these people wanting to resume their normal lives but not being able to do so, thus they begin to suffer emotion changes, with some even considering suicide
Risk factors
People using
psychedelic drugs recreationally are at risk of experiencing HPPD.
Symptoms
The visual
disturbances a person with HPPD may experience include:
- seeing halos or auras around objects
- seeing trails that follow moving objects
- having trouble telling colours apart
- the colour of an object seeming to change in hue
- an object appearing to be moving when it is actually still
- seeing a pattern on an object that others cannot see
- visual snow (seeing snow or static, as you would if you experience poor TV reception)
- the dimensions of an object looking like they are changing
Management and treatment
The following clinical drugs have been found to be
effective in the treatment of HPPD symptoms:
- Lamotrigine (antiepileptic, mood-stabilizing medication)
- Clonazepam (tranquilizer)
Other ways to manage symptoms include:
- avoiding illicit drugs
- reducing stress
- treating related conditions, such as anxiety or depression
All in all, occurrence of HPPD is considered to be
quite rare and because few people have been diagnosed with HPPD, research on
the condition is quite limited.
