What is Spice (K2)?

a dried synthetic cannabis also know as spice or k2

K2 or "Spice" belong to a classification of substances called "Synthetic cannabinoids." These man-made psychotic substances can either be ingested or inhaled.

The common street names for this drug include:

  • Liquid incense
  • Black Mamba
  • Fake Weed
  • Genie
  • Blaze

The National Institute on Drug Abuse further explains that synthetic cannabinoids activate the same receptors in the human body, such as the CB1 and CB2 receptors. While they may have similarities with natural cannabis, these two are entirely different.

Synthetic marijuana produces the following side effects on the body including:

  • Seizures
  • Palpitations
  • Psychosis
  • Violent behavior
  • Suicidal thoughts

The drug stays in your system at varying lengths. Its half-life spans from a couple of days to a few weeks, depending on the body and the amount of drug used in general.

Determining Factors on How Long Spice Stays in Your System

A person suffering from addiction to synthetic cannabinoids may have a harder time eliminating substances from their system due to many factors that come into play.

Let's look into some of these factors in closer detail:

  • Age - Young people are more agile and still have developing organs. Therefore, metabolizing drugs would be easier for them to do compared to older people who have weaker organs.
  • Body mass - People who are physically heavier process substances slower compared to lighter individuals. This will also affect the elimination time for people suffering from drug misuse.
  • Taking other drugs or substances - If you are ingesting other substances, such as alcohol or other prescription medication on top of your addiction to synthetic cannabinoids, you'll have a harder time metabolizing the chemicals off your body.
  • K2 half-life - It takes roughly two hours to rid yourself of the synthetic cannabinoid substance inside your body. It also plays a huge role in how long spice would stay in your system.

Take note that these factors may vary from person to person. It's still best to consult with licensed medical professionals on the best way to deal with the said factors.

What Happens When You Stop Taking Spice?

As you wean yourself from taking Spice, your body undergoes various changes in such a way that there will be the presence of physical manifestations. Drugs like Lexapro also share these traits. These are called withdrawal symptoms.

Withdrawal happens to be an essential part of the various treatment options you receive when you undergo detoxification. It may range from mild to severe, with a timeline that may start for a few days up to weeks, depending on a person's body or capacity.

Here are some of the withdrawal symptoms linked to the drug's use:

  • Palpitation
  • Muscle spams and tremors
  • Anxiety
  • Confusion
  • Headaches
  • Intense marijuana or drug cravings
  • Sweating

Other more serious drug withdrawal symptoms involve the following:

  • Depression
  • Altered behavior/mood changes
  • Psychological issues

When there is no progress with the situation and the individual regresses, interventions may come in handy in helping them recover from their mental health issue.
