Cannabis

  • Key Stage 3
  • Topical

Type: Activity
Learning Strategy: Case study
Topic: Drugs

New Zealand and UK scientists have found that smoking just one joint of cannabis a day puts people at a much greater risk of lung cancer compared to smoking 20 cigarettes a day. In this activity students become MPs. They consider ethical arguments and decide whether or not to completely legalise cannabis.

This activity is designed to be used in conjunction with Simpletons: a tool for teaching ethical thinking. We suggest using Simpletons to teach students how to think from different ethical perspectives. Legalise cannabis then allows students to practise the same ethical styles in a different context.

This activity is in powerpoint. The text on page 2 is fully editable so that you can adapt it to the needs of your students.

11-14 How Science Works:
• 4b consider how and why decisions about science and technology are made, including those that raise ethical issues.

Running the activity

Display page 1. This gives the context and sets the task: decide whether the UK government should legalise the recreational use of cannabis. Tell students that, some forms of drugs are legal, such as alcohol and tobacco, even though they have associated health risks. They are commonly used and are a source of revenue for the government – in the form of taxation (although it can be argued that this revenue does not cover the costs associated with the use of these drugs). Now, ask whether the government should fully legalise the use of cannabis. This legislation raises ethical questions. Today's activity focuses on the ethics of legalising the recreational use of cannabis.
Pages 3, 4, 5 and 6 are posters that summarise one ethical approach each. Photocopy these onto A3 and display in different (accessible) parts of the classroom.
Page 2 gives 12 ethical arguments. Use the arguments in one of the following ways:

EITHER: Copy page 2 two or three times and cut into cards. Give each student – or pair – a card. Tell them to associate their card with an ethical approach and move to the relevant poster. Once there, discuss the arguments with others by the same poster and decide if they are in the right place. Repeat at least once, having given each student a different card.
OR: Ask more able students to devise their own arguments, one or two associated with each ethical approach. Then continue with the activity as described in 'either' above.
Then use page 7 to conclude the activity and assess learning:

EITHER: Students fill in one of the forms/boxes. They display their completed form next to the appropriate poster, and stand by it. Lead a class discussion to decide whether or not the UK government should legalise the use of cannabis.

OR: In groups of 4, each student fills in a different box. The group then decides whether or not the government should legalise cannabis.

OR: Ask students to fill in all the forms/boxes. Lead a class discussion to make the decision.

This is ideal to teach students science and ethics while helping them to develop and evaluate value systems and how to debate topical issues.

Tried this with a year 10 group - they enjoyed discussing the points and enabled them to develop opinions that actually had reasoning. We took a vote before & after and the activity swayed about 1 third of the class.

Resources were very good- prompted good classroom discussion, pupils could see there was no one correct answer,it enabled them to look at it from different perspectives and that they had to make their own judgement backed up with their own reasoning based on fact.
Pupils enjoyed the task.

There wasn't enough arguments only ba one's and they weren't even good arguments becaus they didn't even have reasons, but I think it was quite good because it gave more reasons on the task to keep it illegal. It also got my brain to work

The former pdf files were easy to download. the new ppt files are good that they can be edited but our local servers are weak and take a long time to download. so why don't an option be made either one can download pdf version or ppt version.

EDITOR'S RESPONSE: We recognise this is the drawback - if you have a slow connection. We are investigating whether it's possible for us to post a pdf version as well. We will let subscribers know.

This is a good activity which I used with a class of 4 boys in the PRU where I work. They found it interesting but it only lasted for about 20 minutes due to their preference for kinaesthetic learning! I combined it with a video about drugs and would recommend this acitivity as one which could be used at many levels.
