A disturbing video of Year Nine students of Vaimauga College smoking what appears to be methamphetamine has been going viral on social media. The principal and staff are investigating with the help of the police.

This video shows up to six students of Vaimauga College passing around an empty water bottle filled with pure white smoke claimed to be methamphetamine.

Speaking to Sunday Samoan, Principal Faumuina Taefu Tovio Taefu said this is a bad situation and he was shocked to see the video shared to him by one of their staff members on Saturday morning.

"This is very disturbing and makes the school look bad," Faumuina said.

Faumuina said they would work together with the police to investigate all students involved in this incident.

"This just happened when the school is now on a two-week break," he said.

"But this will not wait, the staff with the help of police because I'm pretty sure they will be involved and so as the assistance from the parents of these kids," he said.

Faumuina said these students if confirmed they have been on drugs, will be expelled from school and let the law deal with them.

The principal said they were keen to know if these students from their school were on meth and they would like to know who is supplying the drugs to these kids.

"I just can't believe that the students involved are from Year Nine and we would investigate who was providing the drugs to the students," Faumuina said.

These students included four girls and two boys. All were seen smoking from this empty water bottle with clear white smoke passing around to one another.

Principal Faumuina said he just couldn't believe that these students would do such a disturbing video, not only allegedly committing a crime while wearing the school uniform but also having the confidence to take a video and upload it on social media for the world to see.

"At the moment I am in shock and we the staff are starting with our internal investigation here at school hence the school breaks for two weeks," he said.

"I don't know where these students have been doing this but I tell you our school makes sure that no student breaks any rules while learning," Faumuina said.

"This shows how life is nowadays with drugs being another number one crime that is destroying not only families, villages, churches and now even schools." 

Police Commissioner Auapa'au Logoitino Filipo was unavailable for comment.
