This research study is looking at the effects of cannabis use on typing, as an activity of daily living. You will be asked to install the kalimbaQWERTY software on your computer as a part of the study to help us understand how you type.

The kalimbaQWERTY software does capture:
- Which keyboard section you use (that is,i.e keys on the left side of keyboard keys, keys on the left side of keyboardright side of keyboard keys, the following modified keys: (shift, ctrl, alt, win/mac key, enter, spacebar, backspace, NA), etc)
- Your typing rhythm and speed

The kalimbaQWERTY software does NOT capture:
- Which specific keys you press or tThe content of what you type.
- This means NO sensitive information will be captured (i.e. passwords, bank account info, etc.)

Your data will automatically be securely transmitted to a secure server. The study is not collecting information on what you type or your passwords. The study is looking at, for example, cannabis effects on typing rhythm and speed.

After installing the software, please type as usual on your computer. Keystroke data (not the content of what is typed) will automatically be securely transmitted to a secure server. When this research study ends, you will be asked to uninstall the software from your computer.

Thank you very much for your participation in the research study!
