Did You Know?

As our Drug Testing Kit UK's Health Science Advisor, reports:

"Different drugs stay in the system for different amounts of time. The length of the effects of different drugs vary greatly. For example, the high from marijuana can last for up to 10 hours, the high from LSD can last 6 to 12 hours, and the high from cocaine can last  15-30 minutes. The same is true for how long a drug stays in the body’s system, even after the effect has worn off. Some drugs such as marijuana will stay in  the system for days; and even months. How long a drug is detectable depends on a number of factors" [1]

This means that if you have staff who abuse drugs, they can often be found out a long time after they have consumed them. In fact, many employees who are given either an announced, or unannounced random workplace drug test, are quite shocked to have a positive test result. This is however, very important for the employer, as they can verify and record the result, thus signalling to the members of staff concerned, that they are aware of their behaviour. Moreover, they can be given a written warning in order to try to prevent the employee from acting irresponsibly in the future.

Furthermore, the employees who have positive results (which show drugs in their system), should be called into the manager's office in order to discuss the matter. They should be directed to, and shown the company's/organisation's mandatory Health & Safety Policy in relation to workplace drug testing (if it exists). Moreover, the employees in question, should be told that at any time in the future, they will be subject to both announced and random unannounced on-site drug tests. And if their contract of employment does not have provision for these aforementioned events, then your company/organisation will need to draw up a suitable legal document for them to sign. Details can be found in Drug Testing Kit UK's Blog Section.

     Synthetic Marijuana

    "Synthetic Marijuana, also known as K2 or Spice, are man-made chemicals that are sprayed on dried plants to be smoked or sold as liquids to be vaporized. This drug is sometimes marketed as “fake weed,” and it is unpredictable and dangerous, sometimes causing violent behavior, vomiting, suicidal thoughts, and rapid heart rate. The results of drug tests for Synthetic Marijuana greatly depend on how frequently the user inhales the drug" [1]

    Renowned for being leaders in the field of workplace and on-site drug testing; and supplying countless companies, organisations, institutions, educational establishments, and medical facilities, across the length and breath of the UK and Southern Ireland, Drug Testing Kits UK is very aware of the availability of synthetic marijuana.

There are severe health effects of synthetic cannabinoids, including breathing problems, muscle damage, heart attack, and kidney failure" [1]
