Zap away cocaine addiction with lasers! or magnets!

brain laserResearchers at the National Institute of Health and UCSF claim to have stopped and started cocaine addiction in rats with the use of laser stimulation to the prefrontal cortex, the brain region where decision making and impulse control take place. “When we turn on a laser light in the prelimbic region of the prefrontal cortex, the compulsive cocaine seeking is gone,” said Antonello Bonci, MD, scientific director of the research program at the NIH’s National Institute on Drug Abuse (NIDA).

Studies with human subjects are already being designed ,according to Billy Chen, the lead researcher. But lasers wouldn’t be used with human participants. Prefrontal cortex stimulation would be achieved through the use of transcranial magnetic stimulation (TMS) which is currently being used as a treatment for depression. It should be noted that the jury is still out on the efficacy of TMS to treat depression, as reported in the journals Current Pharmaceutical Design and Pharmacology and Therapeutics.

This is all very interesting, but addiction is more than biological. People don’t become addicted to a drug because of their neuroanatomy and neurochemical environment. It’s more complex than that. It seems unclear to me what exactly changes in the prefrontal cortex due to this stimulation. Does it make a person (or a rat) more mature and logical in their decision making process? If that’s the case, there may be many uses for this technology! Needless to say, I’m skeptical.

Substance Abuse Treatment Options: Getting Help

substance abuse treatmentCounseling? Rehab? Support groups? How does one know where to start when it comes to choosing a substance abuse treatment program?

First, you’ll want to get a formal assessment from a licensed professional to determine which treatment option is appropriate for you. Some substance abuse treatment options to consider are support groups, inpatient, and outpatient treatment.

AA, NA and other 12 Step programs

Support groups led by peers that focus on helping a person abstain from substances or behaviors.
Pros:  offer additional support and can be a good place to find additional resources and information, free, many locations, various meeting dates and times
Cons: Abstinence is the only treatment goal option, lack of clinically trained support staff, religious undertones, little to no treatment for underlying psychological issues

Inpatient substance abuse treatment

Patients are required to stay in a facility for a pre-determined amount of time varying from 15 to 90 days or more.
Pros: safe, contained environment, trained professional staff, 24/7 support, sometimes the facilities are relaxing and luxurious, intensive treatment, various modalities including individual therapy, group therapy, expressive arts
Cons: expensive (plus you’ll have to take time off work), limited contact with outside support system, intensive treatment, there may be limited availability in your area

Outpatient substance abuse treatment

Patients attend treatment once or several times per week and address underlying issues plus addiction.
Pros: individualized treatment,  local, clinically trained professionals, choice of abstinence or moderation, various modalities to choose from including individual therapy, group therapy, partial hospitalization or intensive outpatient
Cons: some treatment options may be expensive, may not be enough support or treatment for your needs, availability may be limited in your area

A partial hospitalization program involves daily treatment for 6 to 8 hours per day for one to two weeks. This is a good substance abuse treatment option for those who cannot afford inpatient treatment but would like intensive therapy or who live far away from an outpatient treatment program that specializes in the care they need. Intensive outpatient treatment (IOP) involves daily treatment for 1 to 2 hours per day and can last up to several months. This option works well for those who need substance abuse treatment more than once per week or who have time commitments that prohibit them from seeking more intensive treatment. IOP can even be done in the evening after work.


Some people will need to go through medical drug detoxification before starting substance abuse treatment and in some cases it may be a prerequisite for admittance into a program. If you are dependent on a substance, (especially alcohol, opiates or benzodiazepines) it is advisable to detox under medical supervision to avoid complications and discomfort from withdrawals.

Never stop using alcohol or benzodiazepines (Xanax, Klonopin, Valium, Ativan) cold turkey! The withdrawal effects can be severe and life threatening. It is necessary that you detox from these substances under medical care if you have been using them daily and at high dosages.

A note about harm reduction and abstinence: Harm reduction is at the core of all substance abuse treatment programs – abstinence based and moderation management. Harm is reduced by abstaining from the problematic behavior or through reducing negative consequences associated with it.
