Speedy cannabis spit test could spot people driving while high

Researcher from Stanford University, California developed new technology in detecting THC existence. THC is the active compound of cannabis or commonly known as weed or marijuana. The compound can be detected in saliva which is a viscous liquid within mouth.

Shan Wang's breakthrough technology using mobile device utilizes nanoparticle system that clasps THC molecules. Sensor will indicate THC from electromagnetic reaction of the components aftermath.

Several states in America have a differentiation about cannabis utilization regulation. There are twenty three states that allow weed for medical treatment and another four states for recreational use. In contrast, for driving regulation, there are disputable issues because the same concentration of THC has different effect for each person. There is no exact evidence of cannabis use causes bad driving habit. So that, more data are needed to deliver a conclusion accurately. But, Wang' idea of user-friendly system is a promise further of technology. "if it can be analyzed quickly and with known accuracy, and if that measurement can be correlated well with actual impairment, then you've got something quite useful.", the expert says.

Hi Azmi, first if all, linking verbs, these verbs are very minor that are often neglected by a writer, though they may not seem to affect the overall idea of the essay, the sentences are the ones that suffer the most, this is due to the fact that, when a sentence os missing a link, it looses a very vital part to make it a whole sentence and give the exact idea that you are trying to convey to your readers.

To give you examples of this observations, please find below;

- California developed a new technology
- detected inthrough the saliva
- which is a viscous liquid within our mouth.

- Shan Wang's breakthrough in technology
- using mobile device, ( don't forget your punctuation marks too ) utilizes
- states that allow weeds for medical
- In contrastOn the contrary ( contrast - is for color / contrary - is for ideas ) ,

There you have it Azmi, the above are just examples of how else can you enhance your essay. I hope I was able to help.
