Summary
Weed can be relaxing, funny, creative, and social - until it isn’t. In this episode, we look at what weed is actually doing in the brain, why it can calm one person and overwhelm another, and how it can change from something enjoyable into something we start leaning on for out emotional wellbeing.
We explore:
• What actually happens to our brains when we’re high
• What THC and CBD actually are, and how they differ
• Why weed can make some people anxious, hungry, or more creative
• When weed becomes less about fun and more about coping, avoidance, or escape
• How smoking can shape memory, motivation, and everyday connection
• The signs your relationship with weed might be changing

| 0:08.5 | Hello everybody. I'm Jemma Spike and welcome back to the psychology of your 20s, the podcast |
| 0:14.6 | where we talk through the biggest changes, moments and transitions of our 20s and what they |
| 0:20.7 | mean for our psychology. |
| 0:28.0 | Hello everybody. Welcome back to the show. Welcome back to the podcast. It is so great to have |
| 0:33.6 | you here back for another episode as we of course break down the psychology of our 20s back as |
| 0:39.1 | well for an episode. I know a lot of you have been waiting for. Thank you for your patience, |
| 0:44.9 | but I just felt like I felt like we had to wait for episode 420 to do this topic for aesthetic purposes, |
| 0:51.7 | of course. Today we are talking about the psychology of weed. |
| 0:56.6 | I know a lot of people have thoughts on cannabis usage and as a drug, you know, it's obviously |
| 1:02.7 | very easy to villainize, but cultures and societies have been using cannabis for thousands of |
| 1:08.2 | years. It is one of the oldest drugs, oldest plants, in fact, |

| 2:03.7 | two sides to cannabis consumption that mean that it can be as dangerous as it is liberating and |
